Restore protoc version (#3)

bondolo · web-flow · commit d4348179998f · 2022-06-23T13:59:01.000-07:00
Motiviation:
The gRPC example currently fails to build due to missing version for
`protoc` executable. This version is not received from including the
`servicetalk-dependencies` BOM and must be explicitly specified in
this context.
Modifications:
Restore `protobufVersion` property and use it for version of `protoc`.
Result:
gRPC example builds correctly.
