feat: implement base folia support

[0utplay]

Motivation

Folia has been somewhat stable for some time now. Some users are requesting support and even took matters into their own hands by forking CloudNet, so indeed there is some need :)

Modification

Added a new platform-scheduler ext module which enables platform (bukkit / folia currently) independant scheduling capabilities. Made use of the new platform scheduler in the bukkit impl of bridge to properly support Folia there.

Furthermore, Folia was added to the version installer (currently only 1.21.11)

Result

Folia is supported in the CloudNet-Bridge and can be installed using the version installer.

Other context

Fixes #1352
