migrate non-monix modules to cats-effect 3

[ThijsBroersen]

I migrated the core modules to cats-effect 3, looks like it is working. Skipped the monix-related modules but perhaps you find this PR a good start to continue the migration on.

Would be great to get this merged. Without Cats Effect 3 support this library is essentially dead :disappointed:

Thanks for the message @sideeffffect I have released the cats effect 3 module: keycloak4s-admin-ce3 : 3.2.0
