Add setuptools to requirements.in

[suvayu]

Description

The glean parser script uses pkg_resources, and running the glean parser script fails.

According to the release notes for Python 3.12¹, setuptools is not included in a virtual environment by default any more and should be explicitly included.

I don't know what would be the appropriate version, the latest version worked for me. So I used that.

Hey, Thanks for the PR. While i agree with the contents and the premise, i do think this is not the correct place to fix that. If glean has a dependency on that, it should list that.
So i suppose this should be added here: https://github.com/mozilla/glean_parser/blob/main/pyproject.toml
If this breaks your workflow and you don't want to hassle with yet another mozilla repo happy to pass the patch to the team, otherwise they are probably happy to get a pr for that.
Let me know what you think :)

Hi @strseb, thanks for the comment, agree with your analysis. I would be fine with it if you pass along this fix upstream. I only compile the VPN client since it's not packaged for Fedora.
