Added DataFileCategoryService to manage data file categories configuration

[abujeda]

What this PR does / why we need it:
This is my first PR, so not sure there are other changes needed.

From the Harvard Data Commons project, we have a requirement to add a new file tag "Workflow" to the default list of Dataset file tags.

We thought that making this list configurable will provide value as well as meeting our requirements.

Which issue(s) this PR closes:

Closes #8461

Special notes for your reviewer:
N/A

Suggestions on how to test this:
To add a new list of default file tags, eg:
curl -X PUT -d 'Docs,Data,Code,Workflow' http://localhost:8080/api/admin/settings/:FileCategories

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

Is there a release notes update needed for this change?:
Not sure

Additional documentation:

Thank you for the PR, @adaybujeda! This looks good. The Mock tests of the service methods are definitely appreciated.
One quick request, could you please document the new setting in doc/sphinx-guides/source/installation/config.rst, under this section:

.. _database-settings:

Database Settings
-----------------

(this becomes https://guides.dataverse.org/en/latest/installation/config.html#id156, in the formatted version of the guide). Please use the descriptions of other settings there as a model. At a minimum, all it needs is the name of the setting (:FileCategories), a brief explanation of what it does (overrides the default file categories...) and a command line example (the example you provided under "How to test this" would work perfectly).

Thank you again, for your first Dataverse PR! 🥇 😄

[abujeda]

Thanks for the comments @landreev.

I have updated the Database settings docs.

[landreev]

OK, thank you. Please note that I added a simple "release note" directly to the branch: doc/release-notes/8461-filecategories-config.md. This is our standard way of keeping track of new features/important fixes/etc., to be included in the combined notes for the next release.
Please edit it as you see fit, if you want to add any extra information etc.

[landreev]

One last thing, could you please rename DataFileCategoryService.java as DataFileCategoryServiceBean.java, for consistency with how we've been naming our service beans - thank you!

[abujeda]

Thanks @landreev!

I have renamed the service bean.
Release notes LGTM.

[landreev]

OK, perfect, thank you.
I'm moving it along into QA, hopefully will be merged shortly.

[abujeda]

Thanks @landreev 🚀

[landreev]

OK, this is the real last thing for sure: could you please sync the branch up with develop? - The QA are asking all the developers with unmerged PRs to do this manually; with the new release out and the project version having been changed in the main pom file.

[abujeda]

Sure @landreev.
I have rebased from develop. PR updated.
