feature: Allow Avo::NavigationLinkComponent to accept an optional target param

[rickychilcott]

Description

While working on adding out some custom tools, some of the items I'm linking to are provided by other gems (Sidekiq, PGHero, etc.) and I'd like to pop them in new windows. This option will allow me to specify a target of _blank.
