feat: allow forks to use master branch (#3073)

The standard behaviour for master is that it uses the release/version number rather than the latest master. This is designed to prevent modules "version mixing" e.g alerts.sh being on v20.4.0 and alerts_discord.sh being v20.5.0. Version mixing can cause unpredictable behaviour and break installs.

This solution will ensure that only the official the GameServerManagers repo uses this method. This allows forked repos to use custom code in master ignoring the release.
