Parse url regex with proper `re_path` function.

The licence of `awesome-slugify` differs from the project one, so it can't be shipped together.
Two settings to customize the slugify function have been set so it's possibile to keep using `awesome-slugify`.

Jsonfield package name changed back to jsonfield, so dropping usage of jsonfield2.
