ref(onboarding): Rename SCM integration analytics view to onboarding_scm

The SCM onboarding flow was using the generic 'onboarding' view value
for integrations.installation_complete analytics. Rename to
'onboarding_scm' to avoid ambiguity with other surfaces that may use
'onboarding', ensuring clean experiment data.
