ci(e2e): pin emulator versions and fix Azurite compatibility (#725)

Pin all e2e test emulator images to specific SHA256 digests to ensure
immutability and prevent unexpected breakage from upstream changes.

The three emulators (Azurite for Azure, MinIO for S3, and
fake-gcs-server for GCS) were previously using the :latest tag, which
could cause test failures when new versions with breaking changes or
bugs were released.

Using SHA256 digests instead of version tags provides immutability
(ensures we always pull the exact same image), transparency (easy to
verify what's running via digest comparison), and Renovate compatibility
(can still track and propose updates). All pinned SHAs match the current
:latest tag, confirming we're using the same images that were previously
tested.

Updated Renovate configuration to track digest-based updates while
preserving version information in comments for human readability. Fixed
Renovate to scan test directories and handle multi-line regex patterns
for .go files.

Also fixed Azurite compatibility issue by adding the
--skipApiVersionCheck flag. Tests were failing because the PostgreSQL
container images install Python dependencies without version pinning,
which resulted in azure-storage-blob 12.28.0 (released January 6, 2026)
being installed. This version uses API version 2026-02-06 which Azurite
3.35.0 doesn't support yet. The flag allows Azurite to accept any API
version in the test environment.

Note that MinIO is now in maintenance mode and will not receive further
updates, but it has been included for completeness.
