fix(gradle): correct handling of heuristically matched dependency triples

[Churro]

Changes

Adds special handling for an ambiguous parser match that occurs (only) when heuristically matching 3 string values in combination as groupId, artifactId, version.

During parsing it is difficult to find out whether groupId, artifactId and version are parts of exactly one complete dependency string or independent dependency strings. For example, groupId could occur as a simple string or as one or more concatenated variables. The approach taken here is to first interpolate and then decide how to treat the values.

Context

• Closes manager(gradle): no deps detected when 3 dep strings present in the configuration #30234
