Fix vici valve names

[jacob720]

Updates vici valve names from the placeholders they were set to before. The correct names can be found with
caget -d31 BL21B-EA-GIR-01:VALVE1:POSN
caget -d31 BL21B-EA-GIR-01:VALVE2:POSN

Instructions to reviewer on how to test:

1. Confirm names are correct

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}

Great, thanks. This now connects but could you change the names of the enums themselves to more closely match the actual valves?
