perf: add palm support DS-703

[MaferMazu]

Description

This migration PR does the following:

• Update the workflow versions (based on eox-theming migration)
• Remove the Python 3.10 test because when we update the requirements, we add backports-zoneinfo, which causes errors. (Note: that package is in edx-platform too: https://github.com/openedx/edx-platform/blob/open-release/palm.master/requirements/edx/base.txt#L54)
• Add social-auth-core to use social_core without try excepts
• Add timeouts to the request to avoid hanging indefinitely (Ref: https://requests.readthedocs.io/en/stable/user/quickstart/#timeouts)
• Update requirements
• Update the README https://github.com/eduNEXT/eox-core/blob/mfmz/palm-support/README.rst

Testing instructions

The tests were passed. It starts to fail when I update the readme for the length of the PR. For now, I will put the labeler fail in false, but if you think it is too long, I will split the readme update in another PR.

[MaferMazu]

I would like to merge #257, #258, and #256 before merging this.

Everything is working as expected!

I left a little comment in the test cases doc, but nothing else.

@dcoa @bra-i-am, can you help me with a review again?

[dcoa]

@MaferMazu, Is it possible to rebase the branch to update it, instead of generating a merge commit?

[MaferMazu]

@dcoa ready!
