[danlaffan]

This pull request has two changes:

1. Change the Rails 7 version to call 7.0.0.rc1.
2. Fix the underlying code to avoid a default_timezone depreciation warning.

All comments / questions welcome.

Hi @jaredbeck and @morgoth - Sorry for the radio silence. I was stuck on an important bug in my Turbo project, and got it sorted last night after a random piece of inspiration.

I will update this today and take on board the feedback you have both generously provided.

Cheers, Dan.

@jaredbeck @morgoth I have just posted some commits to do the following:

• Update the gemfile to Rails 7.0.0.
• Fix the default_timezone deprecation as suggested.
• Fix another deprecation .to_s(:db) -> .to_formatted_s(:db)

All tests pass on my local machine. Let's see if Github agrees.

Then a new version of the gem is required.
