zig-yaml (cli4bofs dependency) does not support multiline strings ("|")

[mzet-]

Due to limitation of https://github.com/kubkon/zig-yaml we can't use yaml multiline syntax:

examples: |
 Scanning selected hosts and ports:

   tcpScanner str:192.168.0.1:80,22,443
   tcpScanner str:192.168.0.1:100-200
   tcpScanner str:102.168.1.1-128:445,81,8080-8089

Instead we need to use:

examples: '
 Scanning selected hosts and ports:

   tcpScanner str:192.168.0.1:80,22,443
   tcpScanner str:192.168.0.1:100-200
   tcpScanner str:102.168.1.1-128:445,81,8080-8089
'

That is inconsistent with a Python's YAML implementation (used in https://github.com/The-Z-Labs/bof-launcher/blob/main/examples/implant/z-beac0n-console.py) where using:

examples: '
 ...
'

syntax, does not preserves text's structure. Therefore we need to you different syntax for cli4bofs ( ' ...') and different for z-beac0n console (| ...).

Solution is to add multiline syntax support (|) to https://github.com/kubkon/zig-yaml.
