2.5.1 Dec 2024 Bzlmod fix, bazelrun script fixes

This is a bug fix release:

• Fixes an error in the Bzlmod MODULE.bazel of 2.5.0 related to the dev dependency rules_jvm_external #229
• Fixes an issue with the bazelrun script, due to the first line being a blank line #143 (@drmercer-lucid)
• Fixes a packaging problem with the bazelrun script when --nolegacy_external_runfiles is used #227 (@drmercer-lucid)
• Stood up a public test repo for testing rules_spring releases; previously we relied on an internal monorepo for all testing. This will allow us to innovate with rules_spring faster.
