Change access token UI to select dropdowns (#25109)

The current UI to create API access tokens uses checkboxes that have a
complicated relationship where some need to be checked and/or disabled
in certain states. It also requires that a user interact with it to
understand what their options really are.

This branch changes to use `<select>`s. It better fits the available
options, and it's closer to [GitHub's
UI](https://github.com/settings/personal-access-tokens/new), which is
good, in my opinion. It's more mobile friendly since the tap-areas are
larger. If we ever add more permissions, like Maintainer, there's a
natural place that doesn't take up more screen real-estate.

This branch also fixes a few minor issues:

- Hide the error about selecting at least one permission after second
submission
- Fix help description to call it "authorization" since that's what
permissions are about (not authentication)
