Compatibility issue with Ruby 3.1

[nbluis]

Describe the bug
I'm getting an error when trying to run kt-paperclip on Ruby 3.1.

To Reproduce
Running current specs using ruby 3.1 the error occurs.
PS: I suppressed other test results because I had difficulty run the entire spec in my local environment.

$ rspec spec/paperclip/storage/s3_spec.rb:1506
Testing against version 7.0.3.1
Run options: include {:locations=>{"./spec/paperclip/storage/s3_spec.rb"=>[1506]}}
F

Failures:

  1) Paperclip::Storage::S3 with S3 credentials in a YAML file and aliases being set runs the file through ERB
     Failure/Error: YAML::safe_load(ERB.new(File.read(creds.path)).result, [], [], true)

     ArgumentError:
       wrong number of arguments (given 4, expected 1)
     # ./lib/paperclip/storage/s3.rb:430:in `find_credentials'
     # ./lib/paperclip/storage/s3.rb:316:in `parse_credentials'
     # ./lib/paperclip/storage/s3.rb:198:in `s3_credentials'
     # ./lib/paperclip/storage/s3.rb:232:in `bucket_name'
     # ./spec/paperclip/storage/s3_spec.rb:1523:in `block (3 levels) in <top (required)>'

Finished in 0.04137 seconds (files took 1.21 seconds to load)
1 example, 1 failure

Expected behavior
The entire spec work properly on Ruby 3.1

Desktop (please complete the following information):

• OS: Darwin Kernel Version 21.6.0 / Ruby 3.1.2

Additional context
I found this bug when trying to migrate a rails app from Ruby 2.7.6 to Ruby 3.1.
Then I try to reproduce using the project specs but I'm getting some errors running the specs.
Regardless, I was able to reproduce the same error with the spec above.

Apparently the problem is related to the new version of Psych.

can you confirm you don't have same problem with ruby 3.0.4 ?
