Code Review
This pull request modifies pip_compile.bzl to pass the target_compatible_with attribute to the .update target. Feedback indicates that using None as a default value for this attribute will trigger a Bazel type error, as a list is expected. Additionally, the reviewer suggested forwarding the testonly attribute to ensure the target remains compatible with its dependencies.

With this changset we enable users to build and test `//...` in their repositories also with platforms that do not support Python. For example, a user might use Python for tooling and automation, where he develops only on Linux. Then he could set `target_compatible_with` to `@platforms//os:linux`, but he uses C++ for his production code. Where he crosscompiles to other operating systems (e.g. QNX, TriCore). In order to enable this, we need to forward `target_compatible_with` also to the ` also to the also to the `*.update` target.
