fix(gradle): strip single quotes from project names in composite build dependency report

[romain-petit-whoz]

Current Behavior

When using @nx/gradle/plugin-v1 with Gradle composite builds (includeBuild),
createDependencies always returns an empty array. No inter-project static dependencies
appear in graph.dependencies — every Gradle project only has its implicit conf dependency.

As a result, filterAffected cannot propagate changes through the Gradle dependency graph.
Modifying a file in a leaf project (e.g. commons) never marks dependent projects
(e.g. app, service) as affected.

Root cause: processGradleDependencies parses lines of the form:

+--- io.test.project:app -> project ':app'

and stores "':app'" (with surrounding single quotes) in gradleProjectToDepsMap.
But gradleProjectNameToProjectRootMap is keyed without quotes: ":app".

The lookup silently returns undefined — no error, no warning — and the dependency is dropped.

Note: the existing composite build test mock used -> project :my-utils:number-utils
(no quotes), which is why this case was not caught by existing tests.

Expected Behavior

Inter-project Gradle dependencies from composite builds appear as static edges in
graph.dependencies, allowing filterAffected to correctly propagate changes through
the Gradle dependency graph.
