Improve protected branch setting page (#24379)

Main changes:

1. Change html structure of protected branch page, use [`grouped
fields`](https://fomantic-ui.com/collections/form.html#grouped-fields)
instead of `fields` for better margin, and wrap `grouped fields` around
related `field`s, remove unnecessary `<div id="protection_box"
class="fields">` outer div

2. Changed some order of field to make them more categorized, used `ui
dividing header` for categorization and fine tune css.
