chore(tsconfig): update config target and module detection

[joshblack]

This is a follow-up to: #3920

This PR updates some of the options in our TypeScript config to use newer options or fields that help making developing in TypeScript more consistent and predictable. The changes either come from the PR mentioned above or the corresponding article: https://www.totaltypescript.com/tsconfig-cheat-sheet

Changelog

New

Changed

• Update the following options in tsconfig.json
  • Set module to ESNext
  • Set moduleResolution to Bundler
  • Set isolatedModules to true
  • Set moduleDetection to 'force'
• Use tsx instead of ts-node to compile our TypeScript scripts as ts-node was difficult to work with when using these new settings
• Update color2k in order to use their new type declarations

Removed

Rollout strategy

• None; if selected, include a brief description as to why

These are only related to our internal config and should not impact the output of Primer React

Testing & Reviewing

• Review the config settings changed to make sure they're appropriate
• Review the code changes to make sure they are in line with how we want to be writing TypeScript 👀
