go: micro.dev/v4/cmd/protoc-gen-micro@latest: version constraints conflict: about micro

[alex-dna-tech]

proto-gen-micro package by the README must be installed with master version, not latest.

I'll fix this in template
The next step in init is to install protoc-gen-openapi, but as far as I can see it is no longer supported in V4.
New problems are likely to arise as users try to follow the documentation's instructions.

TODO test

• new service create
• make targets
• run service with default values

[alex-dna-tech]

The handler template is not fully compatible anymore. Only can run Call endpoint.
