feat(vcs): clone from the repositories of your GitHub account (#1125)

The Clone Repository dialog lists GitHub next to Repository URL: the repositories of the account gh is signed in to, searchable; picking one fills URL and directory, double-click or Enter clones. Clone URL follows gh's git_protocol. Clone sources are a workbench contribution (registerCloneSource); gh_account_repos needs no project.

Closes #750
