currently, it's trying to save the plugin and then enrich the data from the plugin's manifest:
https://github.com/greenpress/greenpress/blob/main/apps/plugins/server/controllers/manage-plugins.ts#L35

"save" cannot be completed in the database since some metadata is mandatory - but this data exists on the manifest.
so - we should retrieve the manifest before saving, set the mandatory metadata, and then continue to enrich plugin data according to the function that exists (this function needs an existing plugin in DB in order to continue because it binds the plugin to the platform by mentioning its row's ID.
