Removing jsr305 as dependency to verify if the grpc extension works fine

@cescoffier it seems it works fine ;)

[harshmadhani]

@cescoffier would we still require jsr305 as a dependency in grpc runtime if the checks are passed for them without jsr305?

@harshmadhani If we can remove it, let's remove it!

Thanks, @cescoffier !
