key not found: "UPLOADCARE_SECRET_KEY" (KeyError)

[GuillaumeOcculy]

I have this error when I try to run rails server

$ rails server
/Users/guillaume/.rbenv/versions/3.0.3/lib/ruby/gems/3.0.0/gems/uploadcare-ruby-3.3.1/lib/uploadcare.rb:36:in `fetch': key not found: "UPLOADCARE_SECRET_KEY" (KeyError)
Did you mean?  "UPLOADCARE_PUBLIC_KEY"

This is not a ENV problem because I wrote my credentials directly on config/initializers/uploadcare.rb and still have the same issue

Uploadcare::Rails.configure do |config|
  # Sets your Uploadcare public key.
  config.public_key = 'mypublickey' # ENV.fetch("UPLOADCARE_PUBLIC_KEY", "mypublickey")
  config.secret_key = 'mysecretkey' # ENV.fetch("UPLOADCARE_SECRET_KEY", "mysecretkey") 
...

# .env
UPLOADCARE_PUBLIC_KEY=mypublickey
UPLOADCARE_SECRET_KEY=mysecretkey

The only way to fix it right now is to run export UPLOADCARE_PUBLIC_KEY=demopublickey but it is not the solution

Environment

• Library version: uploadcare-rails (2.1.0) uploadcare-ruby (3.3.1) dotenv-rails (2.7.6)
• Language/framework version: rails (7.0.2.3) ruby (3.0.3)
• OS version: OS X (12.3.1)

I figured it out.
If we use dotenv-rails gem, Gemfile should be like this

...
gem "dotenv-rails", require: "dotenv/rails-now", groups: [:development, :test]
gem "uploadcare-rails"

I created a PR #106
