This follow-up addresses the actionable review feedback from PR #40.

What changed

• Read GARAGES3_KEY_ID in the Garage S3 config, with GARAGES3_KEY kept as a legacy fallback.
• Clarified the Garage env var docs so GARAGES3_KEY is described as the key name and GARAGES3_KEY_ID as the access key ID used by Nextcloud.
• Fixed the trusted-domains guidance to use space-separated values, matching the Nextcloud container behavior.
• Added matching notes to the example env file in both English and Portuguese docs.

Why

• The previous config path could start Nextcloud with the wrong Garage credential or fail when only the bootstrap-generated key ID was present.
• The docs were describing trusted domains with the wrong separator.

Validation

• php -l .docker/garages3.config.php
• git diff --check
