[CHORE] Use forked binding library

- Use the forked [binding](https://code.forgejo.org/go-chi/binding)
library. This library has two benefits, it removes the usage of
`github.com/goccy/go-json` (has no benefit as the minimo library is also
using it). It adds the `TrimSpace` feature, which will during the
binding part trim the spaces around the value it got from the form, this
is done before validation.
