HTML format isnt checked

[ImLunaHey]

when pasting an image in Github uses HTML format by default not markdown which seems to be causing a false positive.

example: https://github.com/typescript-eslint/typescript-eslint/issues/11224#issuecomment-2886383607

I came here to report a false negative 😆 https://github.com/the-turing-way/the-turing-way/pull/4274#issuecomment-3012795420

Adding it here as a note for if someone gets a change to look at how html is handled
