Don't install playwright twice (#29302)

1. `playwright/test` is already installed as part of `deps-frontend` on
CI which runs before, so it's better to not install it again (on a
potentially different version), and just use the version from
package.json and add the `deps-frontend` dependency.
2. `PLAYWRIGHT_DIR` is a undefined variable, so I removed it

```bash
$ git show c8ded77680db7344c8dc1ccee76bce0b4e02e103 | grep PLAYWRIGHT_DIR
+playwright: $(PLAYWRIGHT_DIR)
```
