Drop regexes lib (#258)

This was needed until #227 as the Ruby script did not support multiple regexes.

Now that all regexes has been split / simplified in https://github.com/endoflife-date/endoflife.date/pull/4317 and https://github.com/endoflife-date/endoflife.date/pull/4383 the regexes lib is not needed anymore.
