Installation Guide: confusing license language

[donsizemore]

The Installation Guide reads:

Out of the box, users select from the following licenses or terms:

* CC0 1.0 (default)
* CC BY 4.0
* Custom Dataset Terms

however, at least in upgraded installations, only 1.0 is present. I propose that this language be disambiguated a bit to state that additional licenses may be added using provided or custom JSON, to avoid any confusion/expectation that 4.0 should be present.

I'm all for rewording and improving what we have but just below the three bullets there's already some language about how licenses can be added and removed ("You can remove licenses and add new ones."):

Configuring Licenses

Out of the box, users select from the following licenses or terms:

• CC0 1.0 (default)
• CC BY 4.0
• Custom Dataset Terms

You have a lot of control over which licenses and terms are available. You can remove licenses and add new ones. You can decide which license is the default. You can remove “Custom Dataset Terms” as a option. You can remove all licenses and make “Custom Dataset Terms” the only option.

Before making changes, you are encouraged to read the Terms section of the User Guide about why CC0 is the default and what the “Custom Dataset Terms” option allows.

The above is as of 5.10.1: https://guides.dataverse.org/en/5.10.1/installation/config.html#configuring-licenses

As always, pull requests welcome! 😄
