feat: Add best effort test to validate game ID rules (#111)

* [Test] Add best effort test to validate game ID rules

An attempt to implement the rules specified in #108 as a programmatic
test.

* [Test] Refactor ID rules to check if a mod exists after - in game name

This allows fivem to pass the check following rule 8, but could also
cause a false pass in some cases.

* [Test] Add unit tests for ID rule checker

Adds unit tests based on the examples in CONTRIBUTING.md to confirm in
those cases we would allow ID to pass. However these tests don't check
any error cases.

* test/id: Correctly extract protocol names

* games/defs: Fix unreal tournament IDs

* tests: Require game definitions to run ID tests

* tests: Improve comments on ID tests

* tests/id: Combine - seperated numbers

* games/defs: Fix darkest hour ID

* Add/Update badge
