fix: adjust testes for 3.2.0-NIGHTLY

Also, exnteded the `compat` inn tests cases.
Now it's possible to specify matching version not only as starts with
but as greater or equal.

For example:
```
check(
  "input ... ",
  "default expected ...",
  compat = Map(
   ">=3.1.0" -> "expected for version gte than 3.1.0",
   "3" -> "any otherversion that starts from 3"
  )
)
```
