feat(telemetry): bundle open-telemetry SDK so telemetry:test works standalone

multiflexi-cli's telemetry:test command required the OTEL PHP SDK, but
only multiflexi-web5 declared it as a Composer dependency - the CLI
package always reported "SDK not installed" on servers where only
multiflexi-cli was deployed. Add open-telemetry/sdk and
open-telemetry/exporter-otlp (matching multiflexi-web5's versions) so
the deb bundles them like it already does for every other dependency.
