audit all docs updates against source code

[gitcommitshow]

On every PR (in any key projects of the org), if a documentation page content is changed, trigger a technical accuracy check against relevant source code.

1. When a PR is raised, trigger a check that decides whether the PR changes contain docs change
2. If docs change, trigger auditAgainstSourceCode to find technical mistakes
3. Post the analysis as PR comment

Signals to detect whether the changes are related to docs?

• Conventional commit message starts with docs: or readme:
• .md files are generally docs files.
