Remove extraneous apiVersion: "v1beta" in function calling sample

[andrewheard]

Specifying RequestOptions(apiVersion: "v1beta") is no longer necessary in the Function Calling sample since it is the default as of #137.

I don't think it's a bad thing to be explicit and remind people they're using a beta.

My preference would be to close. However, if you feel strongly, I'll approve.

@paulb777 I don't feel super strongly either way. My main argument in favour of removing it is to avoid overriding the defaults if not necessary since we may migrate back to v1 in the future. Could also simplify migration to Vertex AI SDKs since we don't support overriding the apiVersion there.

What are the other platforms doing?

@paulb777 Currently Dart is the only client-side SDK that offers a function calling sample. They do specify v1beta but it only became the default today -- will ask opinions.

[andrewheard]

Dart is planning to remove the v1beta argument in https://github.com/google-gemini/generative-ai-dart/pull/127/files#diff-84d1116bc601acf95035dd6857c2f31fa41e2b7bf3a0e8a1860b313938ab0630L42.

OK, I'm fine to merge. Thanks for checking.
