feat: pgl_backend_s3: add option for no_verify_ssl

[InsOpDe]

As a User I want to be able to ignore SSL Verification (in case the authority is unknown f.e.) so that I can still connect without getting x509 certificate errors.

This PR adds a checkbox where the user can check this option:

This PR also adds the option to use boolean checkboxes with labels via the Formbuilder.

I did not add any translations as the other fields didn't have any as well. I also am missing a contribution Guide

The frontend part of the code you made a change to is currently being rewritten from scratch as we're moving away from React to Vanilla JS. What that means is we can't allow code changes in the frontend side as what you had to change is gonna disappear in the next few months.

I will keep this PR open as we should be able to merge this minus the frontend change to enable that same functionality once the entire migration is done.
