 These tests were added as so:
 
 ```
-git subtree add --prefix src/tests/interop https://github.com/questdb/questdb-client-test.git main --squash
+git subtree add --prefix questdb-rs/src/tests/interop https://github.com/questdb/questdb-client-test.git main --squash

 These should be updated with:
 
 ```
-git subtree pull --prefix src/tests/interop https://github.com/questdb/questdb-client-test.git main --squash
+git subtree pull --prefix questdb-rs/src/tests/interop https://github.com/questdb/questdb-client-test.git main --squash
