x11/ruby-tk: update to 0.5.0

0.5.0 ((2023-11-09)

* Add support for tcl/tk 8.6.

* Removed getMultipleSaveFile since it does not work on any of the offered
  ActiveTcl distros (8.6 and 8.5).

* Fix patterns in extconf to terminate version number ranges.

* Set RUN_EVENTLOOP_ON_MAIN_THREAD to true in more cases.

* Replace st_foreach_check uses with rb_hash_foreach.

* Update widget: Fix mismatch on setting of encoding.  Encoding of Japanese
  demo files are converted from EUC-JP to UTF-8.  But codes on "widget"
  command expect EUC-JP.

* Avoid warning on Ruby 3.2.

* And several bug fixes.
