prompts: drop trailing '?' + add useGitea toggle

Two small things from testing on the Mac:

1. chezmoi appends '?' to every prompt title, so prompts that end in '?'
   came out as '??'. Strip the trailing '?' from every prompt title.

2. Add useGitea boolean prompt (default false) so users who use a
   self-hosted Gitea instance get a recurring reminder to run
   scripts/post/setup_gitea.sh. Quiet for everyone else.

Existing machines will see 'config file template has changed' on next
apply and need `chezmoi init --prompt` once to pick up useGitea.
