Fix Elasticsearch health check URL quoting

[yuandrew]

What was changed

Quote the URL so Compose waits for a successful Elasticsearch response before starting dependent services.

Why?

The shell interpreted the unquoted & in the Elasticsearch health check URL as a background operator. It ran curl asynchronously and treated timeout=1s as a successful variable assignment, causing the health check to pass before Elasticsearch was ready.

With this fix, dependent services actually wait for Elasticsearch to finish starting, preventing temporal-admin-tools from exhausting its retries prematurely.

Go SDK has been seeing a bunch of failures for the docker job, https://github.com/temporalio/sdk-go/actions/runs/37641169691?pr=2733

Checklist

1. Closes

2. How was this tested:

• Confirmed the original health check returns success against a closed port because the shell treats & as a background operator.
• Confirmed the quoted URL returns a failure against a closed port.
• Validated all modified files with docker compose config.
• Started the full PostgreSQL, Elasticsearch, admin-tools, and Temporal stack. Elasticsearch and Temporal became healthy, and admin-tools completed successfully without connection-refused errors.

3. Any docs updates needed?
