CMR-10122: Use EntryId returned by CMR for ID in CMR-STAC

[dmistry1]

Summary

This PR addresses two issues:

1. Removes the custom entryID generation that was previously based on shortName and version from the metadata.
2. Fixes a bug in platform processing where null instruments fields were causing errors.

Changes

• Now using the entryID provided directly from CMR instead of constructing it.
• Updated the platform processing logic to handle cases where the instruments field is null or undefined.

Testing

• Verified that collections are now being returned correctly in the SIT environment.
• Added unit tests to cover cases where instruments are null or undefined within platform data.

This is to fix the issue where if the instrument field was null it was returning an error. It doesn't need comments or anything just pointing it out to reviewers since we chatted about that over DM.

We should add in the test session an assertion to make sure that is fixed
