Update backstage dependencies

There are some outdated backstage dependencies on these plugins that are causing some other versions to be resolved when installing this plugin.

This has a knock-on effect of some transient dependencies that vulnerabilities being installed and being detected by certain tools.

In this specific instance its the dependency of "@backstage/backend-common@npm:^0.20.1": that is requesting `mysql2@npm:^2.2.5` which resolves to `mysql2@npm:2.3.3` and that package has a critical vulnerability warning.

These plugins need to be updated to the latest backstage dependencies.
