SoyTofu deprecation notice refers to non-public migration guide

[dpursehouse]

The SoyTofu class is deprecated and the @deprecated tag in its javadoc says:

/**
 * @deprecated Use SoySauce instead. Apps/framework users should follow this migration guide
 *     go/af-soy-migration.
 */

go/af-soy-migration is an internal Google link and is not visible publicly.

Please replace this with a public link, or include the migration guide in this git repository.

It is included in the migration guide. See g3doc -> dev -> soysauce_migration.

See g3doc -> dev -> soysauce_migration

Please provide a link. As far as I can see there is only a "todo.md" under the g3doc path: https://github.com/google/closure-templates/blob/master/g3doc/todo.md

There is a http://doc/... link in there, but it also seems to be a Google internal link.

Here's a link: https://github.com/google/closure-templates/blob/master/documentation/dev/soysauce-migration.md

Thanks @emspishak

Would it be possible to replace the go/af-soy-migration in the source code with that link?
