refactor(cli): prepare info refactor

[florian-lefebvre]

Changes

• Extracted from refactor(cli): info #14609
• As I worked on refactoring astro info, the scope unexpectedly exploded
• This PR extracts some of the changes that are required by refactor(cli): info #14609 but can be done before:
  • Moves where the polyfill is applied (doesn't matter much, removed in v6)
  • Moves some abstractions as they are not local anymore (eg. not only for astro docs) but shared across several commands
  • Updates some abstractions in preparation for other usages

Testing

Updated, should pass
