while working on #56 (to add more help providers), I realized that we (or I) are doing this the wrong way. the user may agree or disagree with our choices and we have to provide an easy way for the user to change the plz menu elements as he/she wanted not as we want

Describe the solution you'd like
Instead, we can read a 2D array from the user via the config file or the CLI arguments, or both. this array contains the plz menu elements in the same order that we going to display with, the elements of this array will be in this form:

[ commad|fetch|local, "THE COMMAND | THE BASE URL | THE TOP DIR",  "THE COMMAND ARGS | THE URL FORMAT | THE FILE LOCATION FORMAT" ]

OR something similar

Additional context

• if we started to work on this I'll close feat(helper): add more external help providers to plz menu #56
• the PR that'll close this probably will close Add the ability to use more types of manuals/cheatsheets #14 too
