fix: remove notifications for hard-limited prebuilds (#18528)

Browse Source 
Relates to https://github.com/coder/internal/issues/674


Currently, we send notifications to **all template admins** for **every
failed and hard-limited preset**. This can generate excessive
noise—especially when someone is debugging a template and creates
multiple broken versions in quick succession.

For now, we've decided to remove hard-limited preset notifications to
reduce excessive noise.
In the long term, we plan to aggregate failure information and deliver
it on a daily or weekly basis.
