docs: Use 'develop' extra over removed 'complete'

[matthewfeickert]

Description

Resolves #2110

• Update all uses of the removed 'complete' extra to 'develop'.
  • The 'complete' extra was removed when moving to hatchling in PR build: Switch to using Hatchling as build backend #2095, but the 'develop' extra retains most of that functionality.
  • Update the 'complete' extra to 'all' for the Binder postBuild to reduce the number of dependencies that need to be installed.
• Quote the extra for best practice to ensure compatibility across shells.

I'm going to approve and merge this myself to keep things going. As always, PRs approved by a single core dev can be reverted as needed by the rest of the dev team.
