Change to a version of gRPC >= 1.70.0 as the current verison (1.67.1) has a known vulnerability.

[harshapraneeth]

Describe the bug
[Blackduck](https://www.blackduck.com/) (an application security testing and software composition analysis tool) reports that gRPC contains a data corruption flaw in its zero-copy transmission functionality. This flaw could be exploited by a remote attacker to cause a denial-of-service (DoS). The opentelemetry-exporter-otlp-proto-grpc library uses gRPC with a flexible dependency: grpcio >= 1.63.2, < 2.0.0. Updating to a newer version (e.g., 1.70.0) of gRPC would resolve the vulnerability.

To Reproduce
Steps to reproduce the behavior:

1. Perform an analysis using Blackduck.

Expected behavior
The Blackduck analysis should report no vulnerabilities related to gRPC.
