Check for <framework_name>.deps.json when enumerating framework paths (#90035)

Check for <framework_name>.deps.json when enumerating framework paths (#90035)

This adds a check for the framework's .deps.json instead of just the existence of the directory. To avoid extra file checks in the normal/happy path (where all framework version folder are valid), when resolving, it only does the check after resolving the best version match. And if that version directory isn't valid, it tries resolving again without it.
