Python runtime version and other metadata not reported in the Resource Attributes

[mmanciop]

Describe your environment

• Python 3.8.10
• opentelemetry-sdk version 1.11.1

Steps to reproduce
Take the code from https://opentelemetry.io/docs/instrumentation/python/getting-started/, run it, search in the resource attributes for process.runtime.version

What is the expected behavior?
I expect the resource attributes to contain various process.runtime.* keys, including:

• process.runtime.name
• process.runtime.version

What is the actual behavior?

{
    ...
    "resource": {
        "telemetry.sdk.language": "python",
        "telemetry.sdk.name": "opentelemetry",
        "telemetry.sdk.version": "1.11.1",
        "service.name": "unknown_service"
    }
}

Additional context
N/A

It turns out there is even a well-defined spec: https://github.com/open-telemetry/opentelemetry-specification/blob/main/specification/resource/semantic_conventions/process.md#python-runtimes
