- Replace remote query documentation with new Query documentation
- Add redirect from old remote query to new query documentation
- Update remote query usages across docs to use new query usage.
- Add a prerequisites link to test guides pointing to how to setup the testing tools
- Add in the main http / module integration guides the command to run the tests
- Added documentation on how to use Medusa's tools from the `medusa-test-utils` package to create integration and unit tests.
- Added a manual reference on the `medusaIntegrationTestRunner` and `moduleIntegrationTestRunner` functions. Since the typings in the source code aren't very informative, I opted for a manual reference shedding light on the important bits.
Closes DOCS-852
