infra: add check for images in docs

Motivation

As explained in this guide, we should compress images that are added as part of a docs pull request. This sometimes gets forgotten and then a PR gets merged with too large images.

Instructions

We should make this part of the PR process. I’ve added a label called docs-compress-images.

We should write a GitHub action that checks the following:

• Is it a docs PR?
• Has one or more images been added?

If the answer to both is yes, the build should only succeed if the label docs-compress-images is added. Otherwise it should fail.

Reference

We have a similar (yet not exactly the same) use case for the changelog label. You can check it out for inspiration.

@Hard-Coder05 @wicked-smart thank you both for your PR. Please be nice to each other, it’s all good. We don’t assign issues as explained in our Hacktoberfest blogpost.

@Hard-Coder05 I made a comment on your PR.

@wicked-smart it’s great that you’ve started contributing to open source. Let’s leave your PR open for now, until the other one is merged. We explain in the blogpost how to look for issues. If you need help, it’s also explained in the blogpost where to get it 🙂

@Hard-Coder05 ok boss , my bad …relax !!! , as i said i’m quite new to this. I guess one needs to get assigned to make PR . I saw your check didn’t passed , so then fixed it and pushed.

Alright, buddy, please enlighten me on what should i do now…is there a thing called deleting PR or something ?
