[mandiant] Open vocabularies very strange behaviour in production about connectors

[SamuelHassine]

@Megafredo @nino-filigran It seems to be linked to the Mandiant connector not parsing correctly the motivation. If this is just this, no problem it is not critical at all. Thanks @Megafredo for the quick fix.

@nino-filigran it is normal that you can put manually any kind of content in the open vocab, json is still a string. I was fearing more a global issue in the Python library when we create open vocabs. If it is limited to Mandiant I think we can remove the tag critical.

I cannot access this space within production, but I can at least reproduce on demo the fact copy/pasting a json in the attribute name within an open_vocab is possible .

My bad, I thought that this was checked also!
