fix(turnstile): Disable turnstile by default and rename its env (#10129)

### Changes 🏗️
change ``NEXT_PUBLIC_DISABLE_TURNSTILE`` to ``NEXT_PUBLIC_TURNSTILE``
and set turnstile captcha to be hidden by default

if ``NEXT_PUBLIC_TURNSTILE=enabled`` is set, captcha will work and show
on the frontend login/signup/password reset pages
if ``NEXT_PUBLIC_TURNSTILE=disabled`` is set, captcha will be hidden
from the frontend and is not needed to login/signup/password reset
if ``NEXT_PUBLIC_TURNSTILE`` is not set captcha will be hidden from the
frontend and is not needed to login/signup/password reset

This means users who setup AutoGPT locally will not need to deal with
changing the env to hide captcha

#### For code changes:
- [x] I have clearly listed my changes in the PR description
- [x] I have made a test plan
- [x] I have tested my changes according to the test plan:
  <!-- Put your test plan here: -->
- [x] start the platform with ``NEXT_PUBLIC_TURNSTILE=enabled`` set to
enabled and captcha shows
- [x] start with ``NEXT_PUBLIC_TURNSTILE=disabled`` and captcha does not
show and you dont need it to login ect
- [x] start with ``NEXT_PUBLIC_TURNSTILE`` not set and the captcha does
not show and you dont need it to login ect
