Remove support and lifecycle information from rhdh-plugins: Example PR:  https://github.com/backstage/community-plugins/pull/4302

Remove lifecycle and support keywards from package.json, for example from here: https://github.com/redhat-developer/rhdh-plugins/blob/main/workspaces/bulk-import/plugins/bulk-import-backend/package.json#L108-#L109

Remove "backstage.supported-versions" from package.json. 

Make sure to set spec.lifecycle: active to catalog-info.yamls of workspaces (verify lifecycle matches respective marketplace entity). Make sure to only update catalog-info.yaml describing a plugin (usually top level of a workspace, please do not update marketplace example entities.) Example catalog-info.yaml for a workspace plugin: https://github.com/redhat-developer/rhdh-plugins/blob/main/workspaces/bulk-import/catalog-info.yaml#L23

While removing, verify that they match what is defined in their respective marketplace entities and this doc.
