Fix require for frame_screenshots

[jdee]

Checklist

• I've run bundle exec rspec from the root directory to see all new and existing tests pass
• I've followed the fastlane code style and run bundle exec rubocop -a to ensure the code style is valid
• I've read the Contribution Guidelines
• I've updated the documentation if necessary.

Motivation and Context

/Users/jdee/github/jdee/fastlane/fastlane/lib/fastlane/actions/frameit.rb:4:in `<module:Actions>': uninitialized constant Fastlane::Actions::FrameScreenshotsAction (NameError)

And just above that, in frameit.rb, require 'fastlane/actions/frameit', which is the same file. It's not clear why this didn't fail in CI.

Description

Changed the require to 'fastlane/actions/frame_screenshots'.
