Consume hcaptcha and pwn deps (#22610)

This PR just consumes the
[hcaptcha](https://gitea.com/jolheiser/hcaptcha) and
[haveibeenpwned](https://gitea.com/jolheiser/pwn) modules directly into
Gitea.

Also let this serve as a notice that I'm fine with transferring my
license (which was already MIT) from my own name to "The Gitea Authors".
