[24.1] Add galaxy metapackage for installing the latest stable version of Galaxy with pip install galaxy

[natefoo]

This pins versions of all the galaxy* packages, but to mimic the current production best practice/run.sh, should we add all of pinned-requirements.txt? yes

I tried adding all of pinned-requirements.txt to install_requires but it fails because galaxy-data 24.1.2 (and all earlier versions of it) have a pin on social-auth-core==4.0.3 while the pinned-requirements.txt version for 24.1.2 is 4.5.4. We should unpin this in galaxy-data but it won't be possible to build a fully pinned galaxy metapackage until we unpin that and publish 24.1.3 packages.

How to test the changes?
