Update TetheredLaunch.md

[startergo]

Apps with the Debugging Tool Entitlement can call task_for_pid() to retrieve a valid task port for unsigned and third-party apps with the Get Task Allow entitlement set to true. However, even with the debugging tool entitlement, a debugger can’t get the task ports of processes that don’t have the Get Task Allow entitlement, and that are therefore protected by System Integrity Protection.

Launch fails with "Failed to get the task for process xxx"

This application does not have the get-task-allow entitlement. Or this is not a development app.

Jitterbug will output an error if No get-task-allow is checked.
