Remove docker and test network configs

[timjrobinson]

Description

Removes the docker and test network configs as we aren't using these anywhere any more and having the random network ID's in the config enum causes type issues on occasion.

Type of change

• Code refactor / cleanup

How should this be tested?

• Ensure the app loads and runs as expected.

Checklist:

• I have performed a self-review of my own code
• I have requested at least 1 review (If the PR is significant enough, use best judgement here)
• I have commented my code where relevant, particularly in hard-to-understand areas
• If package-lock.json has changes, it was intentional.
• The base of this PR is master if hotfix, develop if not
