Drop `{'no_viewport': True}` from Camoufox template

[Mantisus]

Follow-up: #2053

Remove the workaround that uses browser_new_context_options={‘no_viewport’: True} for Camoufox after the issue at daijro/camoufox#653 is resolved and a new version of Camoufox is released

[Mantisus]

I'm closing this issue since PR #2053 was closed.

The Camoufox compatibility issue is #2051
