William Banfield d5df412b26 proto: update the mechanism for generating protos from spec repo (#7269)
This pull request updates the `protocgen.sh` script to insert the `go_package` option to all of the downloaded proto files. A related pull request into the spec repo removes this options from the .proto files: https://github.com/tendermint/spec/pull/358

This pull requests, along with the related spec PR, aim to move the creation of the `tendermintdev/docker-build-proto` container into the spec repo. This change also relies on several fixes to that container that are made in the PR into the spec repo.

# This script appends the "option go_package" proto option to the file located at $FNAME.
# This option specifies what the package will be named when imported by other packages.
# This option is not directly included in the proto files to allow the files to more easily
# be hosted in github.com/tendermint/spec and shared between other repos.
# If the option is already specified in the file, it will be replaced using the
# arguments passed to this script.
