Please add "data_type" tag to make parsing easier

Please add "data_type" tag to make parsing easier, for example the CVE JSON format has:

"data_type": "CVE" which means you don't have to guess and test to see what kind of data you're parsing. If the OSV ould add a " "data_type": "OSV" to everything that would make life much simpler. Especially if more people start using things like OSV's database_specific field to embed OSV data into other formats (cats and dogs living together, it's turtles all the way down).

Thanks for raising this! In hindsight we should have named our schema_version osv_version or something similar instead, but we are no longer able to change this for compatibility reasons.

A data_type field is a possibility, but I wonder if there are other ways we can infer this without adding another field to the schema, (e.g. with how GSD is using it today).
