Update google-cloud-aiplatform version to 1.72.0 (#760)

Recently the google-cloud-aiplatform library has been updated to version
1.72.0, which fixes typecasting bugs in Function Calling. This affects
many cases in BFCL, so it would be great to use this version of the
library for an accurate score of the model quality.

The changelog describing the bugfix is here:

Thanks!
