IQSS 10390: Multipid UI Fix

[qqmyers]

What this PR does / why we need it: Fixes the issue by adding logic to determine what option will be inherited by a collection - the global default or the value inherited from a parent collection. The PR also addresses the issue with the GET /api/datasets/id/pidGenerator call sometime returning "default" instead of the PidProvider that will be used (as documented in the Guides).

Which issue(s) this PR closes:

• Closes MultiPid UI selector incorrect for sub-collections #10390

Special notes for your reviewer: Suggesting we put this in 6.2 to avoid a bug going out.

Suggestions on how to test this: Have more than one pid provider configured, create a subcollection and verify that the menu of options on the Dataverse/Edit/GeneralInfo pane shows the options, including one that is either the (default) - if no parent collection has a non-default selection - or (inherited...) option - when a parent/grandparent has an explicit PIDProvider setting.
Can also call the API call above and verify that it returns a PidProvider id in all cases.

Does this PR introduce a user interface change? If mockups are available, please link/include them here: see screenshot in inssue.

Is there a release notes update needed for this change?: no - fixes a bug that hasn't yet been released.

nitpick here - should be "given" and maybe put it in the bundle. Also should we add a test to PidUtilTest?

[qqmyers]

done

Just an error label update, and maybe an additional test - see comment.

Thanks for the updates

Works fine but I didn't like how (inherited from enclosing Dataverse) and (Default) are squished...

... so I pushed a fix to add spaces in b196f54

Here's the config I tested with:

    -Ddataverse.pid.providers=fake,foo
    -Ddataverse.pid.default-provider=fake
    -Ddataverse.pid.fake.type=FAKE
    -Ddataverse.pid.fake.label=FakeDOIProvider
    -Ddataverse.pid.fake.authority=10.5072
    -Ddataverse.pid.fake.shoulder=FK2/
    -Ddataverse.pid.foo.type=FAKE
    -Ddataverse.pid.foo.label=Foo
    -Ddataverse.pid.foo.authority=10.1234

Tests are passing. Will merge.
