Add support for java agent file format 0.3 in explorer db

[jaydeluca]

Adds support in the database builder for the new 0.3 file format, which changed the metric type to data_type and added instrument.

Another note, I am deleting the ecosystem-registry entries for the metadata for versions below the latest (2.26.1). The reason for this is because 2.26.1 is the release where I finished populating the base metadata for everything, and I would like to actually use 2.27.0 as the floor of the versions we track and support for the website, since that's when the data will be the most complete.

After this is merged, I will re-run the db builder pipeline with the --clean flag to nuke earlier versions in the database (ecosystem-explorer/public/data/javaagent).

Eventually we can delete some of the transformation code in the java agent watcher and db builder, but we can leave it for now in case we decide we do want to support older versions for some reason.

Pull request overview

Updates the explorer and DB builder to align with the Java agent registry file_format: 0.3 metric schema (renaming the metric field from type to data_type and introducing instrument), and adjusts related UI/test fixtures accordingly.

Changes:

• Update frontend Java agent metric typings and UI rendering to use instrument/data_type.
• Update frontend tests to use the new metric shape.
• Extend the DB builder instrumentation transformer/tests to recognize file_format: 0.3 and transform older formats toward 0.3.
