docs: document azure keyring usage

[tdejager]

Added some short documentation regarding Azure authentication. Could @jslorrma, verify its correctness if you have the chance? Also pulling in @PanTheDev, because I know you wanted to add documentation surrounding this. We can modify/edit as you guys see fit!

LGTM!

FYI: I have added the keyrings.artifacts package to conda-forge staged-recipes and opened a PR to add my package to conda-forge feedstocks. The recipe has an entry-point for the keyring script, so that when the package is available from conda-forge a global installation with pixi global install keyrings.artifacts should be possible, that automatically adds keyring script to ~/.pixi/bin
