Touch ups

This is a list of things to do after getting the packages onto MELPA. We'll do this in one PR to avoid noise.

• Remove old names of faces from README.
• Move faces to own section under Configuration?
• Make new package descriptions consistent with existing packages.

Other things can be added.

Do you plan to submit corfu-prescient and vertico-prescient soon to MELPA?

[okamsn]

I've made the PR for MELPA. I'll update the Vertico wiki once the package is available.

@minad I've updated the Corfu and Vertico wikis with mentions of the new packages.

@okamsn Thanks!
