`sample` typings error

[meff34]

What is the current behavior:
The sample operator allows sampling from unknown to narrower types.

Steps to reproduce:
www.typescriptlang.org/play

import { createEvent, forward, sample } from 'effector'

const emitUnknown = createEvent<unknown>()
const receiveNumber = createEvent<number>()

sample({
  // @ts-expect-error: unused directive ❌
  source: emitUnknown,
  target: receiveNumber,
})

forward({
  // @ts-expect-error: type 'unknown' is not assignable to type 'number'. ✅
  from: emitUnknown, 
  to: receiveNumber,
})

What is the expected behavior:
The "sample" is expected to work identically to the "forward" in this case: throw compilation error "type 'unknown' is not assignable to type 'number'"

Versions:
Reproduces on effector@22.1.2 and typescript@4.5.4

Already fixed in master, I added a test for your case and it has pretty clear error message:

The fix will be published in next minor release
