build(deps): update objstore to the latest

[tritone]

Updates objstore to HEAD. Also transitively picks up updates for the GCS SDK (see thanos-io/objstore#165).

Also removes replace statement pinning google.golang.org/grpc. Issue which was referenced in the comment (grpc/grpc-go#7314) is now resolved.

I had to make the following additional changes to handle breaking changes in dependencies:

• Pin github.com/prometheus/common to v0.62.0 because of a breaking change in the following version. This is a direct dependency so work is required in this repo to unpin.
• Bump github.com/GoogleCloudPlatform/opentelemetry-operations-go/exporter/trace to the latest release in order to resolve a breaking change in an indirect dep.

• I added CHANGELOG entry for this change.
• Change is not relevant to the end user.

Changes

Verification

make deps and make build pass locally. I could use some help debugging the presubmit failures.

Unfortunately there was a breaking change in the main package in objstore: thanos-io/objstore#155

@fpetkovski might have more context, but we need manual changes to fix this.

@tritone do you want to take a stab on resolving? If not, perhaps one of the @thanos-io/thanos-maintainers has time to do the refactor.

We added a new method to the interface, so we probably need to propagate that to all implementations.
