Update Ambassador API with endpoint for retrieving GCZ Version & Build Info

Currently, the GCZ does not offer any method to retrieve version info, whereas this is a standard offering in other OSDU services.

An example of this from the entitlements API:

GET https://{{OSDU_BASE_HOST}}/api/entitlements/v2/info

Response:

{
    "groupId": "org.opengroup.osdu.entitlements.v2",
    "artifactId": "entitlements-v2-azure",
    "version": "0.27.1",
    "buildTime": "2024-08-29T18:44:13.262Z",
    "branch": "v0.27.1",
    "commitId": "e502127941414cbb15aa2ad65e710787f1a502c0",
    "commitMessage": "OSDU Data Platform v0.27.1",
    "connectedOuterServices": []
}

AC:

• GCZ offers a similar /info endpoint to reveal version, artifactId, and git branch and latest commit ID
• This endpoint should not be blocked behind any authentication, as it does not reveal sensitive information and can be useful for initial pre-req evaluation of a GCZ install
