Support ruby 3.2, DEPRECATED File.exists?

[sandraa-nestor]

When I try to generate api docs on ruby 3.2.0 I get an error:

../lib/rspec_api_documentation/writers/writer.rb:17:in 'clear_docs': undefined method 'exists?' for File:Class (NoMethodError)

File.exists? was deprecated in ruby 2.1.0 and has been removed in the ruby 3.2.0

As a workaround, you can add a monkey-patch like:

class File
  class << self
    alias_method :exists?, :exist?
  end
end

Rubocop removes the line entirely as File.rm_rf is supposed to be idempotent and not care if the file doesn't exist
