Make use of version control

[jkarpen]

From Ian:

The scripts being run on the data relay server(s) should be in version control. An early version of the scripts was checked into the project Git repository here, but it has not been kept up-to-date as it has been further developed. These script should:

1. Be checked into version control.
2. Be deployed from the main branch of the Git repository, rather than developed separately.
3. Use basic linter/formatter checks for code quality (e.g., using the ruff linter used by other scripts in the project).
