fix: Update minimum protobuf version to >=6.30.2

[misohu]

What this PR does / why we need it:

This PR updates the minimum required protobuf version in pyproject.toml to >=6.30.2.

The current version range (>=3.20.3,<7) allows older versions like 4.25.6 or 5.26.0 that do not include google.protobuf.runtime_version, which is used by Feast internally. This causes an ImportError when importing modules like FeatureStore.

Updating the minimum ensures that users install a compatible version of protobuf and avoids runtime failures.

Which issue(s) this PR fixes:

Fixes #5457

@misohu Thanks for the report and fix, please modify https://github.com/feast-dev/feast/blob/master/setup.py#L36 and run make lock-python-dependencies-all to compile the requirements.

Hey @ntkathole thanks for your message. Looks like the resolution fails with

× No solution found when resolving dependencies:
  ╰─▶ Because grpcio-tools>=1.56.2,<=1.62.3 depends on protobuf>=4.21.6,<5.0.dev0 and only the following versions of grpcio-tools
      are available:
          grpcio-tools<=1.56.2
          grpcio-tools==1.57.0
          grpcio-tools==1.58.0
          grpcio-tools==1.58.3
          grpcio-tools==1.59.0
          grpcio-tools==1.59.2
          grpcio-tools==1.59.3
          grpcio-tools==1.59.5

          grpcio-tools==1.62.2
          grpcio-tools>=1.62.3
      we can conclude that grpcio-tools>=1.56.2,<=1.62.3 depends on protobuf>=4.21.6,<5.0.dev0.
      And because feast depends on protobuf>=6.30.2 and grpcio-tools>=1.56.2,<=1.62.3, we can conclude that your requirements are
      unsatisfiable.

      hint: Pre-releases are available for `grpcio-tools` in the requested range (e.g., 1.62.0rc1), but pre-releases weren't enabled
      (try: `--prerelease=allow`)

grpcio-tools

You might need to pin grpcio-* to upgraded versions

Hey @ntkathole ok found some version ... now having problems with the make lock-python-dependencies-all getting

Hey, thanks for contributing. Some of the companies are still using 4.25.x. So before bumping to 5.x we need to be really careful about it. Instead. I think a temporary fix should be lower the upper bound for protobuf version.
