Abbreviating journal name fails when the full name has uppercase terms in it (e.g. ACM)

[tzok]

You can reproduce the problem with doi:10.1145/3589263

1. BibTeX generated by crossref.org has a protected term in the journal field: {ACM}

   $ curl http://api.crossref.org/works/10.1145/3589263/transform/application/x-bibtex
   

   @article{Kuschewski_2023,
    ...
    journal = {Proceedings of the {ACM} on Management of Data}
   }
   

2. Because of that, the regular expression to replace the journal field with the abbreviated name fails: https://github.com/bibcure/doi2bib/blob/master/doi2bib/crossref.py#L91

3. In effect, the BibTeX produced by doi2bib has this malformed line:

   @article{Kuschewski_2023,
    ...
        journal = {Proc. ACM Manag. Data} on Management of Data}
   }
   

4. In the end, bibtexparser recognizes the whole section as a comment and not an @article
