Typescript setLocale method have incorrect inner type

[viktor-horacek]

Message is declared like this

type Message<Extra extends Record<string, unknown> = any> =
    | string
    | ((params: Extra & MessageParams) => unknown)
    | Record<PropertyKey, unknown>;

But should be like this:

type Message<Extra extends Record<string, unknown> = {}> =
    | string
    | ((params: Extra & MessageParams) => unknown)
    | Record<PropertyKey, unknown>;

Because with any as default, i am getting params type any

setLocale({
    mixed: {
        required: (params) => 
    }
})

Params should be of type MessageParams

just in case anyone else need this: i was able to pull MessageParams out of the Message type as a workaround for what i wanted:

type MessageParams = Parameters<Extract<Yup.Message<{}>, Function>>[0]

Yup.setLocale({
  mixed: {
    required(params: MessageParams) {
      console.log(params)                  
    },
  },
})

i can open a PR with the suggested change too, but i'm not sure what the impact of this type change would be.
