Rename usage of Dir/File.exists to exist

[ecnelises]

The singular methods were deprecated long ago and finally removed in Ruby 3.2.0.

See ruby/ruby@bf97415

Looking forward to having this merged. We are seeing these deprecations after upgrading to Ruby 3.1.3.

Ruby 3.2 removes Dir.exists? and File.exists? but that will not yet be discovered via tests since FakeFS is used and it creates its own aliases.I have a PR open to update that FakeFS: fakefs/fakefs#482

Also, updating the workflow to test 3.2 would be kind.

Thanks for your efforts @ecnelises . We need this too.

Thanks @ecnelises for this work!

@ddollar hey 👋
I see that this is starting to become a blocker for newer versions of Ruby.
If I may ask, would it be possible to get some approvers' eyes on it?

Thanks in advanced!

just run up against this issue. manual edit of base.rb fixed it locally but next time I update...

[bdescamps]

Any update concerning potential merge ?

[graaff]

There is another File.exists? in spec/foreman_spec.rb

This just fixes the spec, it is still broken in ruby 3.2
