Remove text captchas from Invidious (#5308)

textcaptcha.com seems to be down since April and it does not appear that
service will be restored.

Text captchas can be easily automated using free LLMs, so keeping the
text captcha is more like a gate to create accounts in mass on public
Invidious instances.

It also gives headaches like bots automating account creation to modify
the videos that appear popular page of each instance (since the popular
page is based on the subscriptions of the registered users).
