Feature #21020: Sync sig directory for prism of default gem.

Currently, the type signatures (RBS) for the default gem is not available.
Prism is the only default gem with type signatures, but this number is expected to increase in the future.

As a first step to resolving this issue, I propose including the sig directory of Prism as a default gem in the synchronization process.

I'm fine with this if everyone else is.
