Make the rails:template rake task load initializers

Templates could rely on irregular inflections or external libraries for
instance so we should load the application's initializers when running
the rails:template task.

The introducing commit of this feature is f7f11361 ; the initializers
have never been loaded invoking this task.

Fixes #12133.

 *   Introduce `Rails.gem_version` as a convenience method to return
     `Gem::Version.new(Rails.version)`, suggesting a more reliable way to perform
     version comparison.
