Update Gemfile dependencies (bundle update)

[Splines]

I ran bundle update to update our dependencies according to our Gemfile (which I cleaned up recently in #680 and pinned Gems there). Might be worth checking out if there are new major versions for some gems (in a future PR).

I also updated my local bundler version by executing bundle update --bundler. You can see this in the last line in the Gemfile.lock. The newest version is 2.5.17, released on August 1, 2024.

TODO for myself & reviewers

• Check that everything is still working with the new dependencies.
  We should probably not encounter any problems as we pinned the gems in Clean up Gemfile & pin all gems #680, such that they only undergo automatic minor version upgrades. There could still be a bad apple somewhere...

@fosterfarrell9 Good that we have tests: the update for the js-routes gem here broke MaMpf and you couldn't access some pages in the frontend anymore since Routes. ... was not defined anymore for JavaScript files. Some cypress tests detected this, e.g. your test that the lecture page shows a button.

Instead of fixing the underlying problem during the update, I've pinned js-routes to the older version. This is because there is already a new major version and I don't see the point in investing time here in upgrading a minor version if we could just as well upgrade to the major version soon, see #690.
