Add id to submitSnapshot success response

[gitulisca]

Purpose

This change will add the Snapshot id returned by Dependency Graph when a Snapshot is successfully submitted.

The Snapshot id is useful information to have when troubleshooting Dependency Graph issues as it facilitates the correlation of workflow run (or job) with a particular Snapshot reported in Dependency Graph.

It will also help GitHub Support Engineers to verify whether the canonical Snapshot reporting in our Internal Tooling matches the workflow run discussed in the support tickets.

The expected outcome is that the additional Snapshot Id will be written to workflow run log and summary when actions that leverage the dependency submission toolkit are used. For example, the advanced-security/maven-dependency-submission-action and advanced-security/component-detection-dependency-submission-action actions.
