Backport to stable-4.7: 💔 cherry-picking failed — conflicts found

❌ Failed to cleanly apply da2cf18 on top of patchback/backports/stable-4.7/da2cf1852da925f6d354fd1583ee56df1dcfa0ce/pr-3571

Backporting merged PR #3571 into master

1. Ensure you have a local repo clone of your fork. Unless you cloned it
   from the upstream, this would be your origin remote.
2. Make sure you have an upstream repo added as a remote too. In these
   instructions you'll refer to it by the name upstream. If you don't
   have it, here's how you can add it:

   $ git remote add upstream https://github.com/ansible/ansible-hub-ui.git

3. Ensure you have the latest copy of upstream and prepare a branch
   that will hold the backported code:

   $ git fetch upstream
   $ git checkout -b patchback/backports/stable-4.7/da2cf1852da925f6d354fd1583ee56df1dcfa0ce/pr-3571 upstream/stable-4.7

4. Now, cherry-pick PR Fixed collection upload permissions and css styling #3571 contents into that branch:

   $ git cherry-pick -x da2cf1852da925f6d354fd1583ee56df1dcfa0ce

   If it'll yell at you with something like fatal: Commit da2cf1852da925f6d354fd1583ee56df1dcfa0ce is a merge but no -m option was given., add -m 1 as follows instead:

   $ git cherry-pick -m1 -x da2cf1852da925f6d354fd1583ee56df1dcfa0ce

5. At this point, you'll probably encounter some merge conflicts. You must
   resolve them in to preserve the patch from PR Fixed collection upload permissions and css styling #3571 as close to the
   original as possible.
6. Push this branch to your fork on GitHub:

   $ git push origin patchback/backports/stable-4.7/da2cf1852da925f6d354fd1583ee56df1dcfa0ce/pr-3571

7. Create a PR, ensure that the CI is green. If it's not — update it so that
   the tests and any other checks pass. This is it!
   Now relax and wait for the maintainers to process your pull request
   when they have some cycles to do reviews. Don't worry — they'll tell you if
   any improvements are necessary when the time comes!
