Ruby 3 incompatibility (call to `File.exists?`)

[hakanai]

cane checks currently fail on Ruby 3 because of this call to File.exists?:

cane/lib/cane/file.rb

Lines 21 to 23 in c8d6ce4

	def exists?(path)
	::File.exists?(path)
	end

This now gives a NoMethodError and suggests File.exist?.

Typical Ruby to delete the method with the correct grammar, if you ask me. :(

here is what worked for me, I created bin/run_cane:

#!/usr/bin/env ruby

# Monkey patch for File.exists? to alias it to File.exist?
# https://github.com/square/cane/issues/102
if RUBY_VERSION >= '3.2.0' && !File.respond_to?(:exists?)
  class File
    class << self
      alias_method :exists?, :exist?
    end
  end
end

load Gem.bin_path('cane', 'cane')

Monkey patched that one.
