Use `--gapic_generator_version` to specify the value.

Note that you can specify a `SNAPSHOT` version as long as you have build the SNAPSHOT of gapic-generator-java in your maven
local repository.
Note that you can specify any non-published version (e.g. a SNAPSHOT) as long as you have installed it in your maven
