Add support for rails 7.2

$ bundle install
Fetching gem metadata from https://rubygems.org/.........
Resolving dependencies...
Could not find compatible versions
Because db-query-matchers >= 0.12.0 depends on activesupport >= 4.0, < 7.2
  and rails >= 7.2.0 depends on activesupport = 7.2.0,
  db-query-matchers >= 0.12.0 is incompatible with rails >= 7.2.0.
So, because Gemfile depends on rails ~> 7.2.0
  and Gemfile depends on db-query-matchers ~> 0.12.0,
  version solving has failed.

@sds could you take a look please?

I had to remove rails7.1 as it seems to be causing issues (looks like the latest main is seeing the same issue).

TIA

I haven't seen your pull request. Sorry! Created another one - #66. But it solves the Rails 7.1 issue. It can be copied to yours.

Dear maintainers, could you, please, take a look at our pull requests and release a gem with the Rails 7.2 support 🙏.

No problem @ngrebenshikov as long as it's fixed 👍
