docs: replace TODO placeholders with real content and fix internal links

[Vamsi-klu]

Split out from #33263 (which I'm closing in favor of this), per the earlier discussion about breaking that PR into smaller, focused pieces.

This is the conflict-free, docs-only subset rebased onto current master. It replaces TODO/placeholder markers with valid content, wires up PyObject API references, and fixes several internal links across the build/test guides and the GCP/Snowflake/Omni integration docs. Only changes that apply cleanly to current master are included; files master has since rewritten were left out to avoid clobbering newer content.

Changes (14 files):

• Replace TODO placeholders with real prose: troubleshooting-components, migrating-workspace-yaml, testing-run-status-sensors, etl 6-create-a-sensor, asset-versioning-and-caching, running-a-subset-of-asset-checks, testing-partitioned-config-and-jobs, kubernetes/setup, user-roles-permissions.
• Wire up valid PyObject API references (DataVersion, ExecuteInProcessResult, AssetCheckExecutionContext, JobDefinition.execute_in_process) in place of plain-text mentions.
• Fix internal links/anchors and add missing dedent="4" props in the BigQuery/Snowflake references; replace the placeholder link in dagster-omni.

All introduced links, anchors, and PyObject references were verified to resolve (docs build uses onBrokenLinks/onBrokenAnchors: 'throw'). The core-logic changes that were also in #33263 are intentionally excluded and can be raised separately as focused PRs.

Greptile Summary

This PR replaces TODO/placeholder markers with real prose, wires up PyObject API references for DataVersion, ExecuteInProcessResult, AssetCheckExecutionContext, and JobDefinition.execute_in_process, and fixes internal links and dedent props across 14 documentation files.

• TODO placeholders replaced in troubleshooting-components, migrating-workspace-yaml, kubernetes/setup, user-roles-permissions, etl sensor guide, asset-versioning-and-caching, running-a-subset-of-asset-checks, and testing-partitioned-config-and-jobs.
• Internal links fixed in BigQuery and Snowflake reference pages (updated Snowflake partition materialization links from old /concepts/ path to current /guides/ path; removed stray trailing backtick from BigQuery SQL block); dedent=\"4\" props added to three CodeExample components.
• Omni RST updated replacing a dangling TODO with a link to the state-backed components guide.

Confidence Score: 4/5

Safe to merge after fixing one file where new content was appended below a TODO line rather than replacing it.

In troubleshooting-components.md the bare TODO on line 8 was not removed when the new introductory paragraph was added — readers will see TODO as the first word of the page body.

Important Files Changed

Filename	Overview
docs/docs/guides/build/components/building-pipelines-with-components/troubleshooting-components.md	New troubleshooting content added, but the bare TODO on line 8 was not removed — it renders as visible text immediately before the first paragraph.
docs/docs/guides/build/projects/workspaces/migrating-workspace-yaml.md	Good migration guide content added; bare TODO on line 9 still renders (flagged in previous review thread).
docs/docs/integrations/libraries/snowflake/reference.md	Duplicate paragraphs at lines 104-105, 133-134, and 157-158 where old TODO-comment lines were not removed (flagged in previous review thread); dedent="4" props added correctly.
docs/sphinx/sections/integrations/libraries/omni/dagster-omni.rst	TODO replaced with a working link, but uses a hardcoded absolute docs.dagster.io URL that won't resolve in local/staging builds.
docs/docs/guides/test/testing-partitioned-config-and-jobs.md	PyObject reference for JobDefinition.execute_in_process wired correctly; TODO comment removed.
docs/docs/guides/build/assets/asset-versioning-and-caching.md	TODO link for DataVersion replaced with a proper PyObject reference.
docs/docs/integrations/libraries/gcp/bigquery/reference.md	Stray trailing backtick in SQL code block removed; dedent=4 prop added to CodeExample; TODO comment removed.
