Support :sql schema format in the install generator

[ringe]

This patch will make it easier to use solid_queue when the app is set up with :sql schema format because of unsupported SQL features.

Fixes #621

• Install generator uses schema or structure template based on active_record.schema_format
• Added queue_structure.sql template based on the existing queue_schema.rb template

I've built a script to run any of the "Tests (3.1, sqlite, rails_7_2)" approaches.

The failing tests are not failing because of my patch here, the tests are just not very stable.
I re-run the tests in question and they pass. Re-run the whole file, complete pass.
Sometimes I get skips.

Can I do anything to make the tests more stable?

Thank you!

Hey! Yes, out of the 3, only one test was actually failing, and that's a flaky test already on my radar. The other two failures were Docker container starting errors from GitHub actions, it seems.

I'll try to review this this week, but I'm not sure if I'll get to it 🤞
