Link to dmg in OSX Setting Up a Dev Env is Broken

[MikeiLL]

Steps to reproduce

Read the osx dev env docs and click the link for https://github.com/quodlibet/quodlibet/releases/download/ci/QuodLibet-latest.dmg.

Expected Output

A download

Actual Output

A 404 page

Test System

Which version of Quod Libet?

4.4.0 (through current, I guess)

Which operating system

MacOS 13.5.2 (Ventura)

Additional Information

Looks like these downloads are not ready/intended to be run.

When I have the main branch (release-4.6.0) checked out locally, it errors when trying to call with the 4.4.0 app:

/Volumes/Oggun/Applications/QuodLibet.app/Contents/MacOS/run /Users/mikekilmer/quodlibet/quodlibet.py
    #...
    class InstanceTracker:
  File "/Users/mikekilmer/quodlibet/quodlibet/util/__init__.py", line 53, in InstanceTracker
    __kinds: dict[type, list[object]] = {}
TypeError: 'type' object is not subscriptable

Can checkout with git checkout release-4.4.0 and run or download one of the in-development images and at least with [QuodLibet-latest-v10.dmg](https://github.com/quodlibet/quodlibet/releases/download/ci/QuodLibet-latest-v10.dmg) it os compatible. I was (am) hoping that #4190 would be fixed in 4.6.0, though not so far.
