Rewrite MASTG-TECH-0079

[TheDauntless]

This content is quite outdated and doesn't work for ios 17 / 18

Luckily, it's pretty straightforward with the update of frida-tools; the only thing the binary needs is get-task-allow.

The technique should (imo) explain:

• Loading Frida gadget into an application
• Launching the app and attaching a debugger

Frida is straightforward; just add the frida-gadget on the host and launch as normal (though add a comment about prewarm).
lldb can be done based on flutter/flutter#133465 (comment)

Also add a note on limitations as per https://www.youtube.com/watch?v=TKWSwEGUyH8

Please review (again, there are new changes) https://github.com/OWASP/owasp-mastg/pull/2907/files before proceeding with this ticket

I reused that TECH ID for a new Tech because the content wasn't very valuable given the other changes in the PR

Also I think we should add an actual section about testing on non-jailbroken devices in https://mas.owasp.org/MASTG/0x06b-iOS-Security-Testing/
