Add "activate" phrasing for scripts

[tannisroot]

Only feels natural for the user to say that they want a certain script activated. And the light domain uses "activate" too. Real life use-case: i have a script named "Intercom" that opens intercom door and it feels most natural to me to say "activate" instead of "start" or "run" or "turn on".

Summary by CodeRabbit

• New Features
  • Enhanced the HassTurnOn intent to include "activate" as an additional command option for more flexible script activation.
