(maint) Update pip provider regex

[cthorn42]

When searching for versions of a Pip module a regex we depend on needs to be updated to work with Pip version 24.

Tested this on Ubuntu 2404 x86_64 with a Pip version 24.2 and on Ubuntu 1804 x86_64 with a Pip version 9.0.1, and with this change puppet-agent was able to apply this catalog:

package { 'python3-pip':
  ensure => latest,
 }

package { pandas:
   ensure  => latest,
   provider => 'pip3',
  }

With this change on both OSes and both versions of Pip I was able to install pandas.

Could you add a link to this PR about where the regex came from?

The regex we're switching to here, 9!0dev0+x, comes from Github user notatallshaw, as suggested in this thread: pypa/pip#12852 (comment).
