Installing the latest extension does not make the "databricks" cli available because of incorrectly configured path variable.

Steps to reproduce the behavior:

1. Install the Extension: v0.3.14
2. go to terminal and type "bricks" it will run, now type "databricks" it will not run
3. Run Databricks sync from the extension and see that it finds a path to the correct binary
4. Echo $Path and you will see the path from 4 is not correcty copied over.
