action: lint is mandatory but doc changes don't need it

[v1v]

Motivation/summary

lint check is mandatory regardless of the changes, so ci-docs.yml is workaround to skip checks when the CI does. not run for docs changes.

Otherwise, it might mislead contributors since the lint check will not allow merging docs only PRs.

Is it cool if I backport this change to 8.7 as well? I'm seeing the same problem in that branch.
