fix: update internal registry from legacy to new revamp registry (#317)

## Problem
The release creation process was failing with 404 errors when trying to
fetch images like cadvisor:6.6.2517 from the legacy internal registry.

## Root Cause
Recent changes in the main sourcegraph repo migrated from legacy
registries to new 'revamp' registries, but the deploy repos were still
hardcoded to use the old registry.

## Solution
- Replace `us-central1-docker.pkg.dev/sourcegraph-ci/rfc795-internal`
with `us-docker.pkg.dev/sourcegraph-images/internal`
- Updated both release.yaml and batch-change/release.yaml
- Tested and confirmed images exist in the new registry

## Test Plan
- Validated that cadvisor:6.6.2517 exists in new registry but not in old
registry
- Successfully tested sg ops update-images command with new registry
- Confirmed this fixes the original 404 errors during release creation
