- Fix tests in opensearch-model: rspec mocks expects keyword arguments when
  using the syntax `with(options: 'value')` but the real code uses a `options`
  hash. Fixed by explicitly defining a `Hash` as the argument: `with({ options:
  'value'})`

- Add support for Rails 7.1 (wip).

- Fix pagination tests by including the `OpenSearch::Model::Importing`
  manually. Not sure why this is necessary.

- Fix `searching_search_request_spec.rb`: explicitly expect a options hash
  instead of keyword arguments when stubbing.

- Fix
  `opensearch-model/spec/opensearch/model/adapters/active_record/import_spec.rb`
  tests.

- Fix activerecord & mongoid tests.

- Fix namespaced_model_spec test.

- Remove support for unsupported Rails versions. At the time of writing from
  Rails 6.1 upwards is still supported [1].
- Set minimum supported Ruby version to 2.5 since this is the minimum supported
  version by Rails 6 [1].
