Bump dugite to 2.5.2

[DeeDeeG]

Description of the Change

• Bump dugite to 2.5.2
• Bump whats-my-line to a dedicated branch where the only new change is bumping dugite to 2.5.2
  • (avoiding the superstring bump on whats-my-line master, as I'm not set up to sync the superstring bump across all three packages that depend on it at once just yet)

Looking at the CI, the baseline state of things isn't super great but I don't see anything that looks truly like a new issue as of this PR.

• Number of failing tests is identical on the Ubuntu-20.04 runs of both latest master commit and for this PR (18).
• Number of fails is up 19 --> 22 for the ubuntu-latest test runs, but I didn't see any categorically new-looking ones. I can see that it's specifically a different number of failures (looks like CI flakiness/run-to-run variance?) in the sub-tests of some problematic test topics (integration: file patches and WorkerManager).
  • Reading the most into this, it could be a tiny perf regression leading to more timeouts in these tests, but perf is so variable on CI machines for GitHub Actions I would not read this much into it, personally.
  • Out of hundreds of assertions, only increasing by 3 within existing categories that have multiple flakes each run already seems like run-to-run noise that could be ruled out by running another CI run, I guess. I don't think it's worth it, though, I don't really have time to mess with it at the moment :/.
• macOS and Windows test runs, on master branch even before this PR, (consequently also for this PR of course) are broken, failing to even install the dependencies (such as for Python 3.12 issues, etc.)
  • These are too badly maintained to even meaningfully look at at the moment :/ They need a fix when someone gets the chance.

Basically working on my machine, didn't throw any errors on startup, was able to sync latest commits from the remote for my local clone of pulsar repo.

I'll merge this and ask @Daeraxa if this works on their ARM Linux machines before doing a PR to core?

(How to test: ppm install https://github.com/pulsar-edit/github after this merges, or clone this repo and ppm install + ppm link).

EDIT: Thanks for review!!
