kernelci.api.models: use StrictInt for version fields

[JenySadadia]

For int fields, pydantic internally converts fields to integer if possible e.g. request field value "2" is converted to 2 in the FastAPI request handler for model parsing. That's why KernelVersion.version is converted to int when received by API.
Instead of relying on implicit data type conversion for int field, use StrictInt to enforce defined data type in the request itself.

Causing exception during kci tools use on staging:

@nuclearcat that's supposedly related to something in the staging environment using python < 3.10. @pawiecz and @JenySadadia know about this in more detail. Related: #2381

[pawiecz]

As @hardboprobot noted, this indeed looks like Py <= 3.10 issue.

@nuclearcat Please provide more details to track down this issue (e.g. command called, exec env - kci-easy?).

[nuclearcat]

Yes, it can be reproduced also in latest kci-easy during build on debian bullseye.

Right - I'm afraid importing models in helpers used by cli will be a no-go until we drop 3.9 entirely

Ouch

True. Now, we are left with 2 options: one is type cast model fields in the tarball service but that is leaking model info. Another option is we can use KernelVersion.translate_version_fields in api.main.post_node handler itself to translate fields before parsing. We are using these kind of handlers for get_nodes atm.
