@sbillinge fixed news item, ready for review

btw @alisnwu I closed this before reading https://www.diffpy.org/diffpy.utils/examples/toolsexample.html but there I saw no clear information about how to update the default user information. I would put it as an enumerated list to make it clearer. there are at least 4 different ways of setting these things with more or less permanence. Make it as an enumerated list. But also discuss with and example how to updage your default file using a text editor.

Also, is this a typo?

from diffpy.utils.tools import get_user_info
package_metadata = get_package_info("my_package")
