Stop including all Rails gems

[langalex]

Summary

By only depending on railties, optional rails gems are not pulled
in automatically, leaving apps with fewer dependencies.

Motivation and Context

By depending on rails, cucumber-rails forces apps depending on it to pull
in all Rails gems, including optional ones such as actioncable
or activejob. This leaves apps more bloated than they have to be.

How Has This Been Tested?

Tests are still passing.

Types of changes

• Bug fix (non-breaking change which fixes an issue).
• New feature (non-breaking change which adds functionality).
• Breaking change (fix or feature that would cause existing functionality to not work as expected).

Checklist:

• I've added tests for my code.
• My change requires a change to the documentation.
• I have updated the documentation accordingly.

We made a change a bit ago (As we had both of railties / rails) to remove railties. Evidently we should have just removed rails.

Could you make this change in all other relevant locations and add a changelog entry

[langalex]

@luke-hill thanks will do. Can you clarify what you mean by "all other relevant locations". I don't think it's necessary for example to change the dependency for all the Gemfiles.

[langalex]

can this be merged?

[luke-hill]

Could you update the relevant locations that also have rails. I think there's some internal testing gemfiles and a couple of other places.

https://github.com/cucumber/cucumber-rails/tree/master/gemfiles here is a bunch of Gemfiles with rails in them.

[langalex]

changed the Gemfiles and tests are green.
