Target latest version of grpc gem (1.62.0)

This MR updates the grpc and grpc-tools gem dependencies to target the latest version, 1.62.0.

We found when working with the gitlab-labkit gem in the customers-dot project that the grpc gem (a dependency of gitlab-labkit) can lead to compile errors when bundling earlier versions. We updated CustomersDot in https://gitlab.com/gitlab-org/customers-gitlab-com/-/merge_requests/9559 to update this dependency to the latest, but discussed in https://gitlab.com/gitlab-org/customers-gitlab-com/-/merge_requests/9559#note_1821171939 also updating the minimum version in this gem as well.

Example of the error that may occur when bundling an earlier version of grpc on MacOS:
