Ruby 3.2 support (File.exists? has been removed)

[amiel]

Describe the bug

Ruby 3.2 removes File.exists?. File.exist? should be used instead.

To Reproduce

Run sord defs.rbs with ruby 3.2.

Expected behavior

I expected no exception.

Actual behavior

I get the following error:

[ERROR] undefined method `exists?' for File:Class

Additional information

File.exists? was removed here: https://github.com/ruby/ruby/commit/bf97415c02b11a8949f715431aca9eeb6311add2.

I haven't provided a ton of extra detail in reproduction steps because I believe this is a straight-forward case. Please let me know if it's not so straight-forward and I can provide more specific information.
