Snippet in Dashboard for setting up qpi-driver does not upgrade pre-existing qpi-driver

[Tinitto]

Describe the bug
On creation of a driver, the systemd snippet shown for python (could also be for other languages) does not
upgrade/downgrade an already existing qpi-driver and thus it raises errors if the expected version is incompatible with the pre-existing one.

To Reproduce
Steps to reproduce the behavior:

1. Install an older version of qpi-driver e.g. uv tool install --python 3.12 "qpi-driver[cli,aer]==0.0.36"
2. As admin, go to 'http://127.0.0.1:8090/#drivers'
3. Click on 'Register Driver'
4. Feed in details including language: 'python', kind: 'qiskit_aer ( Aer Simulator)'
5. Click the submit button
6. In the snippets that are shown, copy the one for systemd
7. Go to your terminal if you are on a systemd enabled computer and run the snippet.
8. Check the logs of the driver installed journalctl -u <name-of-service> -n 25
9. You will see errors like 'No such command 'process'. ' which is true for qpi-driver v0.0.35

Additional context
It seems QPI_DRIVER_VERSION which was probably originally passed as part of that snippet is no longer passed.
It is supposed to be got from /api/op/version GET to the go server, I think.
