fix(TacitRed-Defender-TI): Change API versions to match working SentinelOne pattern

Changed API versions from 2025-09-01 to 2023-04-01-preview for:
- contentTemplates (Function App and Playbook)
- contentPackages

This matches the working SentinelOne and CrowdStrike solutions that
are successfully loading playbooks in Content Hub.

Reference: PR Azure#13267 (SentinelOne) and PR Azure#13269 (CrowdStrike)
as requested by Microsoft reviewer
