Remove CAP_NET_RAW requirement from documentation

Since we now use command-line ping (setuid root) instead of surge-ping
library, the agent no longer requires CAP_NET_RAW capability.

Reverted documentation changes from previous commit that added the
capability requirement.

 ## Troubleshooting
 
-### Agent Crashes with Segmentation Fault (Exit Code 139)
-
-This typically occurs when the container doesn't have the `NET_RAW` capability required for ICMP ping:
-
-```yaml
-cap_add:
-  - NET_RAW
-```
-
-Add this to your `docker-compose.yml` under the agent service. Without this capability, the agent will crash when attempting health checks.
-
 ### Agent Not Connecting
 
 - Verify the API URL is correct (accepts http://, https://, ws://, or wss://)
