Key online not found

[blegat]

BibLaTeX now supports @online but when it is used with Bibliography.jl, I get KeyError: key "online" not found from check_entry(fields::Dict{…}, check::Symbol, id::String) from BibInternal/src/bibtex.jl:51.

I think a main issue here is already mentioned in
JuliaBibliographies/BibParser.jl#8
namely that until now, the parsing ecosystem is mainly focussing on BibTeX, while @online is a BibLaTeX type.
