Set up diamond numtracker so that we can use the training rigs with it.

We want to migrate the training rigs to use the new numtracker path provider, to do so we need to configure numtracker and then replace the path provider in the training rig module with the following:

```
from dodal.common.visit import StartDocumentBasedPathProvider
set_path_provider(StartDocumentBasedPathProvider())
```

## Acceptance Criteria
- The training rigs can run a count scan using the StartDocumentBasedPathProvider and diamond numtracker
