Remove module commands in favour of explict environment variables

[rtuck99]

Fixes #1426

Post 9.33+, GDA no longer has many variables in its environment and these are not exported to the run_hyperion.sh script when it is spawned. Therefore the script no longer has access to the module command and consequently ZOCALO_CONFIG is never defined because dials is never loaded.

Instructions to reviewer on how to test:

1. Hyperion can still start with latest GDA master
2. Hyperion can still start with previous GDA master

Checks for reviewer

• Would the PR title make sense to a user on a set of release notes
