simplify_regex handles named capture groups incorrectly

Description (last modified by Tim Graham)

For example using a regex from Django Rest Framework docs:

>>> from django.contrib.admindocs.views import simplify_regex
>>> simplify_regex(r'^(?P<version>(v1|v2))/bookings/(?P<pk>[0-9]+)/$')
'/<version>)/bookings/<pk>/'

The closing parenthesis in the output is unexpected.

Escaping the / does not seem to help.

@cancan101
If you change your regex to ^(?P<version>v1|v2)/bookings/(?P<pk>[0-9]+)/$ it will work as expected (both the regex and simplify_regex).

But yes, simplify_regex needs to be fixed.
