Unable to get xdebug working

I've followed the [instructions](https://hub.docker.com/r/automattic/wordpress-xdebug) for both my `docker-compose.yml` and VSCode but I'm having trouble getting XDebug to work.

I opened a shell into the `wordpress` docker container and verified that `XDEBUG_CONFIG` is set to `client_host=host.docker.internal`.

VSCode is listening for XDebug but none of my breakpoints are actually triggered.

Just for fun, I ran `phpinfo()` and it seems like remote debugging isn't turned on.

I'm assuming I'm doing something wrong but I'm not sure what.
