Upgrade Mastodon

Stages

all branches refer to those in NeuromatchAcademy/mastodon unless specified otherwise.

Sync the glitch-soc-main branch to glitch-soc/mastodon:main: Open the branch page and click "sync fork"
- If there are any local changes that make a conflict, they can be discarded - this branch is supposed to just be a local copy of the upstream main branch that doesn't reflect our local changes, we will handle that in the next step.

Create a pull request from glitch-soc-main to merge-upstream
- Resolve conflicts, ensuring that changes we have made locally are preserved when possible.
- If it is not possible to preserve a hack, eg. because the relevant feature has been deprecated, update the corresponding feature page and include that in the pull request description
- Don't try and fix failing tests here - that would edit the glitch-soc-main branch, which will then be overwritten on the next fork fix.
