doc(episys): format test-setup and current status blocks for clarity and consistency

- bold current status for clarity and add spacing for better readability
     - Wrap processes in the test setup block inside code blocks as they were rendered as GitLab issues
     - Remove extra spacing in the test setup block

 For launching the multi-UE for NSA mode, there is a provided test script in the
 public EpiSci GitHub multi-ue-proxy repository. However, a brief outline of the
 test set up is included below.
 
-    If running multiple NSA UEs in a single machine, you will need to launch
-    multiple LTE and NR UE processes. For example, to launch a 2 NSA UE scenario
-    there will be a total of 7 processes running for this particular scenario.
-    These processes are LTE UE #1, LTE UE #2, NR UE #1, NR UE #2, eNB, gNB and the
-    proxy. A detailed description of the launch processes can be found at
-    [GitHub Repository](https://github.com/EpiSci/oai-lte-multi-ue-proxy/blob/master/README.md)
