Update to Gradle 8.3, and update all other deps. (#946)

* Update to Gradle 8.3, and update all other deps.

* Fix tests

* Lazily download decompilers, generate version constants to ensure they are synced between the build and Gradle.

Each decompiler has a configuration, this allows the version to be changed at a later date if needed.

* Fix typo :)

* Oh so many versions
