Warn about unspecific parking=yes

[Famlam]

What steps will reproduce the problem?

Validate an item with amenity=parking + parking=yes (example: ​https://www.openstreetmap.org/way/496842012)
There are 6k occurances of parking=yes on OSM at the moment

What is the expected result?

Warning that parking=yes is a very unspecific tag. Being a 'subtag' of amenity=parking, parking=yes is always the case, but the purpose of parking=* is to specify the type of parking.
(It is also warned about on the ​wiki)

What happens instead?

No warning

Please provide any additional information below. Attach a screenshot if possible.

Could be added to the warning throwWarning: tr("{0}={1} is unspecific. Please replace ''{1}'' by a specific value.", "{0.key}", "{0.value}"); in deprecated.mapcss
