Allow more custom version when used with corresponding custom regex

e.g.

• version with prefix (uat-1.2.3)
• any other version structure if there is at least an int for major, minor and patch in this order (see added tests)

• This change assumes that the provided custom_regexp will always include capturing groups. Consider adding a check to confirm that match.groups() is not empty, or update the documentation to clearly state that a capturing group is required in the regex.

version_str = '.'.join(map(str, match.groups()))
