Add extra information for mime type "text/comma-separated-values"

[landreev]

This is a 1-2 issue.

Most CSV files are identified as "text/csv". But we also accept "text/comma-separated-values" (as an ingestable format).
However, we only keep a "pretty", display type for "text/csv". (the mime display type properties bundle needs to be updated).
Also, we don't have a file extension mapping for this type. (this means if you download the original, or uningest, the filename extension "csv" will be lost).

Alternatively we can change "text/comma-separated-values" to "text/csv" when saving the original file info in the db.

Updating this for @landreev, as text/comma-separated-values=Comma Separated Values was added to MimeTypeDisplay.properties in commit 5a19537 on May 2, 2019 as part of #2202, released in 4.15.

In the context of Croissant, specifically comparing output from Kaggle vs (upcoming) output from Dataverse, @goeffthomas made this observation:

"I see an encodingFormat of text/comma-separated-values. Kind of curious about that since I think text/csv is more the MIME type that's on https://www.iana.org/assignments/media-types/media-types.xhtml and https://developer.mozilla.org/en-US/docs/Web/HTTP/Basics_of_HTTP/MIME_types "

I think he's right. text/csv seem much more common than text/comma-separated-values (1 million vs. 35k hits on Google respectively). Plus the specs above and https://en.wikipedia.org/wiki/Comma-separated_values all seem to point to text/csv being the preferred type.
