fix: Room.getEventLog() may return string

[WyattSL]

Brief Description

Room.getEventLog(true) will return a string.
The current type definitions dictate that Room.getEventLog() will always return EventLog[]. This is not the case.
This PR should correct this oversight.

Checklists

• Test passed
• Coding style (indentation, etc)
• Edits have been made to src/ files not index.d.ts
• Run npm run dtslint to update index.d.ts

While Typescript has some limitations when dealing with overload function signatures: the built-in tool type Parameter and ReturnType only infer types from the last overload (see playground ), I think we do not need to be that strict. Therefore, I think we do not need to care about the order of overloads here.
