Update "java-environment" dependency to support Java 23

Description:

Just an FYI:

Gradle version 8.10+ officially supports Java 23. The current gradle version is 8.12 in the pacman repo.

Please update the dependency from java-environment<=21 to java-environment<=23 to reflect this.

Proposed Change:

The PKGBUILD should be updated as follows:

...
depends=(
  ...
  'java-environment<=23'
  ...
)
makedepends=(
  ...
  'java-environment>=8'
  ...
)
...

This ensures compatibility with the latest supported Java version.

Thank you!
