MX Bluesky 651 fix energy changes

[rtuck99]

Dodal changes for DiamondLightSource/mx-bluesky#651

See MX-bluesky PR DiamondLightSource/mx-bluesky#676

Instructions to reviewer on how to test:

1. Energy changes work on beamline
2. Unit tests 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}

Thanks! This may change with some of my suggestions on the mx-bluesky side but given the current structure this is good
