Released version of tonic_health contains blobs

## Bug Report

### Version

tonic_health: 0.12.3

### Platform

Unrelated, code is uploaded on crates.io

### Crates

Tonic-Health

### Description

While reviewing a dependency update for tonic-health I noticed that it contains a binary file: https://diff.rs/tonic-health/0.12.2/0.12.3/src%2Fgenerated%2Fgrpc_health_v1.bin

That is not desirable as it makes reviewing dependencies harder. It also might hide potential attacks.
In this case I believe the blob is just the binary representation of the proto file and that it was accidentally uploaded to crates.io. Please consider to explicitly exclude this file for future updates.
