Download kotlin-compiler-2.4.0.jar, kotlin-compiler-embeddable-2.4.0.jar,
and kotlin-stdlib-2.4.0.jar from Maven Central. Add 2.4.0 to the VERSIONS
list and update MODULE.bazel via bazel mod tidy.
The extractor does not yet compile against 2.4.0 due to removed APIs
(valueParameters, extensionReceiverParameter, getValueArgument, etc.).
Version-specific compatibility shims are needed.

Also removed the version check step, as a version not existing will give
a 404 any way later on, and that was adding a delay.
The cache is stored in a `.kotlinc_zips` and will be cleaned up by
`--clear`.
