⚙️ [Maintenance]: Remove unsupported zizmor secrets allowlist config

[Marius Storhaug (MariusStorhaug)]

This removes stale secrets-outside-env allowlist configuration from the zizmor config so the workflow uses only suppression mechanisms supported by the current Super-Linter/zizmor version.

Changed: zizmor configuration cleanup

The repository no longer carries the unsupported rules.secrets-outside-env.config.allow block in .github/linters/zizmor.yaml.

This avoids keeping dead configuration that cannot be applied by the currently bundled zizmor version and keeps the linter config aligned with actual runtime behavior.

Technical Details

• Removed the rules.secrets-outside-env.config.allow section and its test secret entries from .github/linters/zizmor.yaml.
• Kept existing template-injection ignore settings unchanged.
• No functional action/runtime behavior was changed; this is a linter-config maintenance cleanup.
