[jaeger] Re-add anonymous Elasticsearch access support

The `storage.elasticsearch.anonymous` option was added in PR #442
(chart v0.67.1) but was lost when the chart was rewritten for Jaeger v2.

The elasticsearch.env helper unconditionally injects ES_USERNAME and
ES_PASSWORD with defaults (elastic/changeme), which breaks AWS
OpenSearch deployments that use VPC-level access without basic auth.
AWS rejects the basic auth Authorization header with a 403 because
it expects SigV4 format.

Setting `storage.elasticsearch.anonymous: true` now skips injecting
ES_USERNAME and ES_PASSWORD, restoring the behavior from #442.
