chore: update npm scripts and remove `/scripts` tsconfig

[Parsium]

Proposed behaviour

• Remove generate-proptypes script since it has been refactored to a babel plugin.
• Remove tsconfig.json from /scripts directory - which has been causing the following typescript error: Cannot write file because it would overwrite input file TS when the file is opened/carbon is built
