Hi Team,

Originated from #9376

Currently some markdown files contains HTML <img> tag to display images, and these should not be allowed. Instead we need to use Markdown ![]() syntax to display images.

Note: Some of these tags are in code blocks, so don't required to change them.

• Add new PR check that checks edited markdown files for <img> tag, and it should ignore the ones inside code block

• Make PR check required, PR can't be merged when it fails

Thanks

Hi @babakamyljanovssw

Curious...

1. Does this Issue include finding existing errors?
   OR
   it will work only for new PRs?

FYI - I've fixed all HTML syntax to be Markdown, leaving just the ones inside code blocks.
#9415

You may need to recreate a bad syntax to test out

This will work only for new PRs to avoid merging invalid content
