Do not rewrite project version in BeamModulePlugin

[kennknowles]

The intended project version source of truth is gradle.properties. It is set statically to either -SNAPSHOT when on a non-terminal commit or non-SNAPSHOT on terminal RC commits.

This change eliminates one place where that source of truth is both duplicated and violated.

Discovered when this behavior broke 2.51.0 RC builds by adding -SNAPSHOT to them.

Running some internal tests too, to check that it plays nice with Google's build system wrapper of Beam's build (and I'll just fix internal breakages, since IMO this is obviously correct for Beam)

Yup, passed global presubmit
