docs: update Module Resolution.md

[HamdaanAliQuatil]

Closes #2863

- What I did

Update Module Resolution.md to include clarification that types and typings are synonymous during module resolution in TypeScript.

- How I did it

• Added a note under "How TypeScript resolves modules" mentioning typings is also permissible in package.json
• Under relative import pt. 4, mentioned typings within parenthesis.
• Under non-relative import pt. 4, 12, and 20, mentioned typings within parenthesis.
• Added a note under "Things to look out for" pt 3, indicating that the output may contain a typings field.

Typings is the older and largely deprecated name for this field, I feel like the team discussed this and opted to not include it in a few places during the tsconfig refernce also - so this PR probably isn't neededIMO

Yeah; I don't think we want anyone using typings at this point.
