Jmprieur/folder renaming

[jmprieur]

Purpose

The folder names were too long and had spaces.

• Renamed them,
• updated the README.md so that the links work
• updated the .gitignore so that unwanted files are not proposed to staging

Does this introduce a breaking change?

[x ] Yes. Breaks links we would have previously shared. But this is preferable to do it now
[ ] No

This PR applies Kalyan's suggestion.
It's is pretty mechanical and should be easy to review

[kalyankrishna1]

We can omit "Call", right? What other purpose a sample will have with Graph other than calling it :)

[jmprieur]

Let's keep it.

[kalyankrishna1]

also save two letters by using just graph instead of 'MSGraph. We only care about one graph now, so the MS` prefix can be omitted

[jmprieur]

AAD Graph is still there and for a few years. We want to promote MSGraph, but let's avoid being ambiguous.
