Add usage syntax to prompts from file or textbox

[w-e-w]

Description

• Add usage syntax to prompts from file or textbox
  add markdown at the collapsed by default

• make process_boolean_tag case insensitive

Screenshots/videos:

room for improvement but better than nothing

notes

• I did not perform any test to see if all of these arguments still works this is just adding documentations
• I wonder if it's possible to add more arguments by hooking into XYZ grid, the idea is that if someone implements an XYZ axis it will also get added to the script
