www/ruby-patron: update to 0.13.4

0.13.4 (2025-02-27)

* Format README a bit better using code fences
* Depend explicitly on base64 for running tests
* Remove C code used for Ruby support below < 2.4 (GVL unlock etc.) and drop
  support for these versions
* In tests, close Tempfiles before allowing libcurl to use them (cookie jar)
* Fix incorrect ptr type in uses of curl_easy_escape / _unescape
* Define methods on Session as private instance methods from C instead of
  privatising them from Ruby
* Speed up the /slow endpoint test
* Remove use of curl_easy_reset. This should fix the bug with sessions
  resetting each other's state during session_free
