Added examples for Acronym task

[Leefrost]

Hi guys,

I propose a small change to the task description - Acronym / C#.

It's a little bit hard to understand what will be an incoming phrase after Techies love their TLA (Three Letter Acronyms)!. I got the clue only after I ran the test. I think it will be more helpful if you can provide some examples of incoming phrases to clarify the possible inputs

I have added simple ones, I did not touch the test data. Also, I added an example with '-' to avoid splitting text just by space.

E.g:

...

Help generate some jargon by writing a program that converts a long name
like Portable Network Graphics to its acronym (PNG).

For example:

Incoming phrase	Output
As Soon As Possible	ASAP
Liquid-crystal display	LCD

Thanks and stay safe!

I like the idea! The instructions are generated from a central source of data: https://github.com/exercism/problem-specifications/blob/main/exercises%2Facronym%2Fdescription.md Could you open a PR in that repo? Once the instructions have been updated there, we can auto-update them here.

Done. Related PR to that repository - #1984
