fix(telemetry): count IDP template data (#11720)

# Which Problems Are Solved

The total number of configured IDPs seemed of.
We were counting only the IDP table for non-templated IDPs.

# How the Problems Are Solved

Add a count trigger migration for the IDP template table.
Entries will be counted under the existing
`ResourceCountIdentityProvider`

# Additional Changes

- none

# Additional Context

- Reported internally
- Implemented in #9979
