liboqs "standard" branch: YML format breakage

[baentsch]

When adding the "standard" pqcrystals code into oqsprovider the documentation generator logic failed as the previously int field "nist-round" has been changed to a string in this branch:

https://github.com/open-quantum-safe/liboqs/blob/3cca41957593db65b5acf6da772f28fa7ede2aa3/docs/algorithms/kem/kyber.yml#L17

Error triggered here.

We may also move this issue to oqsprovider, @bhess, if you agree it is one and should be fixed -- unsure whether there or here, though.

@praveksharma : Please decide whether you'd need proper (O)ID documentation for the interop event. If so, this issue needs to be resolved to properly create it. Otherwise, please review/approve/merge #260 to use the oqsprovider "interop-test" branch at the IETF event(s).

If allowing a string isn't an issue beyond parsing, I'd tend to update the parser in oqs-provider.
