Add command line example for finding hatch config file location

[sosey]

Wandering through the tutorial guides - in the hatch guide it might be nice to add the command line example for finding the location of the config file from the command line without opening a file browser. I'll submit a PR for this addition which also adds a comment showing folks you can find help for the config command. Sometimes it's nice to introduce folks to both the cmdline and gui way to approach finding information.
