fix: export const plugin schemas instead of defaults

[mirceanis]

What issue is this PR fixing

relates to #1318 / #1317 / #1315

What is being changed

The plugin schema generator is using export const schema = {...} instead of export default {}. This also requires the imports to change. I also took the opportunity to export the regenerated schemas from the relevant packages as well as to remove any reference to the previous JSON outputs.
