Add support for projects user-feedback endpoint to be compatible with sentry
Despite using the embedded JS widget, Sentry offers an API endpoint for manually submitting user feedback. https://docs.sentry.io/api/projects/submit-user-feedback/
This is not yet implemented into GlitchTip. Having this option would be a huge benefit for all those who do not or cannot use that embeddable JavaScript widget and nonetheless want to capture user feedback.
