Shokofin Dev 5.0.5.3

Update your plugin using the dev manifest or by downloading the release from GitHub Releases and installing it manually!

Changes since last build:

chore: Update manifest category in read-me file. (Skip CI)

misc: Update install instructions in read-me file.

revert: Revert "fix: replace semaphore with actual lock object":

It did not like that we were attempting to release the lock from another thread because of the async behavior inside the lock, so reverting back to semaphores.

This reverts commit 7162ef8.
