Separate suggested builders from default trusted builders

[colincasey]

Summary

This PR replaces the SuggestedBuilder struct with a KnownBuilder struct that contains the same details + the following boolean flags:

• Suggested
• Trusted

These flags can be set on a KnownBuilder to control if it should be displayed as a suggested builder and/or be added as a default trusted builder.

With these changes, heroku/builder:20 has also been removed from the suggested list but remains as a default trusted builder.
