New queue_schema.rb file hardcodes Rails version

[fractaledmind]

After #321, Solid Queue can't be added to any new Rails 7.2 applications. I just reported this problem with Solid Cache in https://github.com/rails/solid_cache/issues/211, and this will have the exact same problem:

bin/rails aborted!
ArgumentError: Unknown migration version "8.0"; expected one of "4.2", "5.0", "5.1", "5.2", "6.0", "6.1", "7.0", "7.1", "7.2" (ArgumentError)

          raise ArgumentError, "Unknown migration version #{version.inspect}; expected one of #{versions.sort.join(', ')}"
                ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

I stumbled into this preparing my workshop for EuRuKo next week, where we are spinning up new Rails 7.2.1 apps and installing the Solid gems.

Oops, so sorry! We're running it with Rails 8, and I didn't think of that 🤦‍♀️ .

The new schema is completely compatible with Rails 7.1, which is the minimum version required to use Solid Queue, so I'll just revert to that.

Perfect. Thanks. And no worries, this is exactly the kind of tiny little bug that inevitably sneaks thru. One of the wonderful things about open source is that the collective community will do a much better job of finding all of these cases than any one individual. Excited to see things coming together for Rails 8 tho!

@fractaledmind would you mind double-checking that the last main works fine for you? 😅 I'll ship v.0.8.1 with if so.

[fractaledmind]

Yes. bin/rails solid_queue:install followed by bin/rails db:prepare DATABASE=queue worked

Awesome! Thank you so much 🙏
