Subject: [PATCH] mattermost: fix version-regex and support webapp update

The version-regex was incorrect, and we need to update the
Mattermost webapp in tandem with the git repository.

nix-update-script looks at the `offlineCache` attribute for yarn
apps. Bit of a hack, but this lets nix-update pull the webapp
at the same time it pulls the git repository and go module hash.
