Address jhump/protoreflect deprecations introduced by v1.17.0

As we bumped our github.com/jhump/protoreflect/desc dependency to v0.17.0 we decided to postpone addressing the deprecations this specific version introduced.

Specifically:

• github.com/jhump/protoreflect/desc is now considered deprecated.

This package is now deprecated. Though use of this package is still needed in order to use a handful of other packages in this repo, many usages should instead prefer the "google.golang.org/protobuf/reflect/protoreflect" package in the Protobuf runtime. In a v2 of this repo, this package will no longer be present.

• github.com/jhump/protoreflect/desc/protoparse is now considered deprecated.

This package is now deprecated. Most usages should instead prefer the "github.com/bufbuild/protocompile" package. There are some behavioral differences that we hope to address with additional API and enhancements to protocompile. But the protoparse package here is just a veneer on top of protocompile and we plan to do as little maintenance as possible here. In a v2 of this repo, this package will no longer be present.

As a result we have a couple of //nolint:staticcheck comments ignoring those deprecations explicitly. Those can be found in the following files:

• lib/netext/grpcext/reflect.go
• lib/netext/grpcext/conn_test.go
• js/modules/k6/grpc/client.go
• js/modules/k6/grpc/client.go

Definition of done

We have replaced the deprecated packages import with their more modern counterparts, and the nolint statements have been removed.
