Add execute_queries matcher

[hugopeixoto]

This matcher is analog to the query assertions available since rails 7.0.

#2817

[hugopeixoto]

There are a bunch of checks failing, but they don't seem related to this PR. For example:

+Finished in 0.00374 seconds (files took 2.32 seconds to load)
+1 example, 1 failure
+
+Failed examples:
+
+rspec ./spec/lib/fixture_set_blob.rb:4 # blob creates a blob from a sample file

Maybe I could do match_unless_raises and delegate it to the query assertions instead of reimplementing it. This would be better because I wouldn't be duplicating the SQLCounter query.

Also, I'm missing docs. The matcher should at least be added to the readme, and I need to figure out how those work in rspec.

I would be leaning towards expect { }.not_to execute_queries, but an obvious use for this is compound expectations (and/or).

Check the /features directory for examples.

That’s how we do it for most other matchers.
