Added support for both LegacyChatService and TextChatService in regards to player targetted binds

[Krcnos]

This pull request adds support for both LegacyChatService and TextChatService in regards to player targetted binds. By default newly created games utilise TextChatService now and having this on doesn't support the .Chatted player event so the bind functionality therefore needs to be updated to dynamically support both.

Please run the Stylua formatter on these changes, as stylua violations will cause CI to fail

Otherwise these changes look good to me. I'm happy to merge if they pass manual tests (by wil) and CI.

Installed stylua and committed changes it made, hopefully that passes
