Quote selection of itemized or enumerated lists with additional spaces

Quote replying to a list adds 4 extra spaces in front of list items. That then gets rendered as code blocks in Markdown, e.g. take following lists

* item1
* item2

1. enum1
2. enum2

And see comment [below](https://github.com/github/quote-selection/issues/62#issuecomment-3022686016).

No source files or tests are named. Start by reproducing the list-quoting behavior described in the issue and inspect the linked comment for details; done means quoted itemized and enumerated lists no longer gain four spaces or render as Markdown code blocks.
