Replace health check SSM

[ngachung]

#351 has been superseded by new requirements as captured in https://github.com/unity-sds/unity-monorepo/tree/main/schemas/health-service

Looks like the key needs to be changed to "/unity/shared-services/component/data-catalog/" and 2 URLs are needed.

{
    "componentName": "Data Catalog",
    "healthCheckUrl": "https:/....",
    "landingPageUrl": "https://..."
}

healthCheckUrl can be the public facing API Gateway catalog URL which stac browser uses.
landingPage can be either api gateway's open API json page or stac browser page.

healthCheck is collections URL (let UCS figure out how to pass creds). landingPage is stac browser.

This is the result.

{"componentName":"Data Catalog","healthCheckUrl":"https://d3vc8w9zcq658.cloudfront.net/data-sbx/collections","landingPageUrl":"https://www.dev.mdps.mcp.nasa.gov:4443/data/misc/stac_entry"}

But it cannot end with /
