fix(build): configure GMavenPlus 4.3.0 to detect Groovy in test scope (liquibase#7539)

* fix(build): configure GMavenPlus 4.3.0 to detect Groovy in test scope

GMavenPlus 4.3.0 introduced stricter Groovy version detection that fails
when Groovy is only available in test scope. This adds Groovy as a plugin
dependency and sets includeClasspath to PROJECT_AND_PLUGIN so the plugin
can detect Groovy while keeping it in test scope for the project.

* fix(build): scope GMavenPlus compile goal to module with main Groovy sources

GMavenPlus 4.3.0 fails when the compile goal runs on modules where Groovy
is only in test scope. Instead of using workarounds, this properly scopes
the goals:

- Parent POM: only test-related goals (compileTests, removeTestStubs)
- liquibase-extension-testing: adds compile and removeStubs goals since
  this is the only module with main Groovy sources
