Subject: [PATCH] Fix `data` property definition in @feathersjs/errors

`data` is described in TypeScript definitions as always defined property, while from [the actual implementation](https://github.com/feathersjs/feathers/blob/c838d8bc4b8a78cb90a2d299bfe4f7b6b8d8c2f8/packages/errors/lib/index.js#L8) it can be undefined.
This PR fixes that definition to be according to actual code.
