[Bug]: Incorrect makefile usage of environment variable

[Yuzobra]

File Name

Makefile

What happened?

When running the make load_test command, the RUN_SERVICE_URL environment var is being used as $RUN_SERVICE_URL, when the correct usage should be ${RUN_SERVICE_URL}, which is causing an incorrect interpolation.

Relevant log output
