[GITEA] Configurable clone methods

Adds `[repository].DOWNLOAD_OR_CLONE_METHODS` (defaulting to
"download-zip,download-targz,download-bundle,vscode-clone"), which lets
an instance administrator override the additional clone methods
displayed on the repository home view.

This is purely display-only, the clone methods not listed here are still
available, unless disabled elsewhere. They're just not displayed.

Fixes #710.
