Fix javadoc for "resolvable" in JsonProjectDependencyRenderer

[candrews]

In the html dependency report's json, the "resolvable" field is not a boolean; it is of type RenderableDependency which is an enum of FAILED, RESOLVED, RESOLVED_CONSTRAINT, UNRESOLVED.

Context

The javadoc is wrong and that is never good :)

Ideally, we should improve the report by replacing resolvable with something like resolveState. But that could be considered a breaking change.

gradle/subprojects/diagnostics/src/main/java/org/gradle/api/reporting/dependencies/internal/JsonProjectDependencyRenderer.java

Line 176 in cd7ce5b

map.put("resolvable", childDependency.getResolutionState());

Our recommendation is to either accept this PR as-is if we do not want to risk the breaking change but file an issue so that a later proper fix can be done, most likely around a major release.

@ljacomet This is entirely internal, so we could change it.
