Update gRPC version to 1.60.2 to address vulnerability concerns and fix data plane integration tests

[rohanshah18]

Problem

1. The gRPC netty version 1.58.0 has vulnerability.
2. I was still seeing some failing CI tests for data plane operations.

Solution

Updated the following dependencies version from 1.58.0 to 1.60.2.
"io.grpc:grpc-protobuf"
"io.grpc:grpc-stub"
"io.grpc:grpc-netty"

Compatibility matrix for grpc-netty and netty-tcnative-boringssl-static can be found here: https://github.com/grpc/grpc-java/blob/master/SECURITY.md#netty

Also as a part of this PR, I have reduced the delay that is set after upserting vectors in the integration tests to 90 seconds instead of 120 seconds and for updateAndQueryPodTest, I have followed the same pattern as serverless indexes to upsert once and run all of the tests after the upsertion.

Type of Change

• Bug fix (non-breaking change which fixes an issue)
• New feature (non-breaking change which adds functionality)
• Breaking change (fix or feature that would cause existing functionality to not work as expected)
• This change requires a documentation update
• Infrastructure change (CI configs, etc)
• Non-code change (docs, etc)
• None of the above: (explain here)
  Dependencies were updated so it doesn't qualify for bug fix but instead security fix.

Test Plan

Ran integration tests on local a good couple of times and on the CI. Fixing configure index test is in flight and will be a future PR from @austin-denoble.

Thanks for upgrading these dependency versions and reducing the wait time in these tests. 👍
