**Summary:**

Functions depending on function-sdk-python 0.6.0 are giving a segmentation fault.
When (re)running the tests for this module, the following is shown:

```
runtime_version.py:98: UserWarning: Protobuf gencode version 5.29.0 is exactly one major version older than the runtime version 6.30.2 at crossplane/function/proto/v1beta1/run_function.proto. Please update the gencode to avoid compatibility violations in the next runtime release.
```

Apparently when renovatebot opened a PR with a bump up on `protobuf` version,
the major version change violated the constraint with `grpcio-tools`, which
has the following dependency:

```
Collecting protobuf<6.0dev,>=5.26.1 (from grpcio-tools==1.71.0)
```

This makes incompatible to have different versions of protobuf for the `build`
venv and the `generate` one.
