(Migrated from github.com)

The previous regex required at least one dot in the hostname, which prevented users from using localhost, IP addresses, or single-name hostnames.

Updated regex now supports:

Domain names (example.com, subdomain.example.com)
localhost and single-name hostnames
IPv4 addresses (192.168.1.1)
IPv6 addresses ([::1], [2001:db8::1])
Optional port numbers (:8080)
Paths and query parameters

Fixes the first issue in the repository.
