Bug report:

Installed on Ruby 3.0.0 and ran with error:

• Expected Behavior:

• Actual Behavior:

Don't work

• Steps to Reproduce:

  1. Install gem
  2. run i18n_linter command on a shell

• Version of the repo:

master

• Ruby and Rails Version:

Ruby MRI v3.0.0

• Rails Stacktrace: this can be found in the log/development.log or log/test.log, if this is applicable.

I think in Ruby 3 the "mime/types" gem was removed from the bundled gems. If I open an irb session and type require 'mime/types' it fails with same error.

[megatux]

After installing

gem install mime-types

I'm able to use the i18n_linter comment, so we should add it to the dependencies, I guess.
