make dataset types translatable and capitalized consisently #10517

Before this commit, the facet looked like this...

Dataset Type
(3) Dataset
(2) software
(1) workflow

... that is, "Dataset" was capitalized but "sofware" and
"workflow" were not. This commit fixes this, making all types
capitalized, and it makes the values translatable in other
languages. However, it does nothing to address some confusion
that Search API users will feel. They'll get back the capitalized
values but will need to pass in the lower case version (in English)
to narrow their search results.
