TypeError on every save: settings file name uses __name__ (ST3/4) #4

Claude reports:

The package's default setting is never loaded on Sublime Text 3/4, so saving any .rb file raises a TypeError.

Sublime Text build 4215, Windows. The package is not in Package Control's Install Package list here, so I copied the files from the repo master into Packages. I opened a .rb file, changed it and saved. The console showed:

RubyCheckOnSave.py, line 15, in run
    child_process = subprocess.Popen(args, ...)
TypeError: expected str, bytes or os.PathLike object, not NoneType

Cause: sublime.load_settings(__name__ + '.sublime-settings'). On ST3/4 __name__ is RubyCheckOnSave.RubyCheckOnSave, so it looks for RubyCheckOnSave.RubyCheckOnSave.sublime-settings, which does not exist. ruby is then None and Popen gets [None, "-cw", path].

Fix (tested): sublime.load_settings('RubyCheckOnSave.sublime-settings'). After this change the setting is read and the next save fails only because /usr/bin/ruby does not exist (see the next issue).
