Match the greeter on the part of the tagline that is not the pitch

The acceptance harness waits for the installer greeter by looking for
"Opinionated", which the tagline no longer contains: it now reads "Beautiful,
Fun & Agentic Linux by DHH". Every scenario the harness drives fails at the
first screen with

  Timed out after 300s waiting for screen: Opinionated

five minutes into a run that never gets further.

Matching "Linux by DHH" instead. That is the half of the tagline naming the
product rather than describing it, it is common to the old wording and the new,
and OCR reads it cleanly off the greeter. A tagline is marketing copy and will
be rewritten again; the product name is what the test actually means.
