CI: disable jsonschema tests due to NVD data errors

[terriko]

• related: Replacing the jsonschema tests? #1438

The json schema tests are flaky because NVD sometimes provides
non-compliant data. Currently the 2021 yearly file does not pass.

Users wishing to run these checks can still do so locally, but the value
of running failing tests in CI seems minimal so they're being disabled.

at line 177 we can safely remove -n json -u latest.
It was added in #1425
edit: Just saw the reply under #1438. So let's do that change in a separate PR.

Ok with removing it.

What do you think about adding some kind of info to test_json.py so that if someone runs it manually it reports that running the test might result in an error due to non-compliant data?

NVM, #1441 does what I mentioned in my previous comment.
