[DominicOram]

Fixes #871

Instructions to reviewer on how to test:

1. Confirm tests still pass

Checks for reviewer

• Would the PR title make sense to a scientist on a set of release notes
• If a new device has been added does it follow the standards
• If changing the API for a pre-existing device, ensure that any beamlines using this device have updated their Bluesky plans accordingly
• Have the connection tests for the relevant beamline(s) been run via dodal connect ${BEAMLINE}

Looks okay, there's a reference to i04_1 in the docs which I'll change now. What was broken about i04_1.py ?

Any _1 beamlines don't work as we don't pick up the different prefix i.e. #760. It's not obvious because it's actually connecting to the i04 PVs when you run dodal connect i04-1. We don't actually do anything on i04_1 anyway so it seems a bit silly keeping it around when it's broken and not used.
