Converted src/messaging/create.js from JS to TS

[NickAwrist]

Resolved issue #16 , Convert src/messaging/create.js from JS to TS.

Changes

• Converted as many variables in the create file to types. Some include number, string, boolean, and a custom interface to handle the data being passed through, MessageData.
• Added proper return types such as Promise<void>, Promise<MessageData, and Promise<boolean>.
• Suppressed some linting errors due to untranslated JavaScript.

  Tests

• Ran and passed npm run lint , with the only eslint silencing was related to "Messaging" being an any type
• Ran and passed npm run test
• Ran ./nodebb start without error.
