emails: Add onboarding_zulip_guide_url to the "unspecified" org_types.

Update the onboarding_zulip_guide email functionality to handle cases
where there is no dedicated marketing page for the organization's
type or when the type is unspecified. In such cases, the email now
includes an introduction text inviting users to explore Zulip features
and provides a link to https://zulip.com/use-cases/.

fixes #26868.
