E-prop optimizations

[akorgor]

This PR primarily introduces optimizations to improve the runtime of the e-prop algorithms. Additionally, it resolves git check errors, updates the reference, and introduces changes to ensure deterministic computations.

Note that all commits prior to Replace insert with emplace_back for efficiency are part of PR #3721, on which this PR builds. Thus, this PR is blocked until #3721 is merged.

Very nice, approved!

@jessica-mitchell This PR almost exclusively changes references to papers and some figures. I have reviewed the small code changes. Could you quickly check that the documentation updates are fine?

@akorgor I noticed that the see also sections are empty in the model docs; i dont think this is a problem worth blocking a pr, but you may want to remove it (I can take a look later as I thought we had something autogenerating those)

@jessica-mitchell thank you for pointing this out. Actually, I could move the sections listing the other e-prop models there.

We just discussed that this issue will be addressed later and not within this PR.
