Bump the default DiKTat version

Use the latest major release - 1.0.1. The previous default version 0.4.0
started causing build failures because of the copyright rule. DiKTat
tests started failing after the new year 2022. It is not entirely clear
why the tests started failing, but the error behaviour changes when
adding a dummy copyright header to Kotlin source files. Example header:

```
/*
    Copyright (c) My Company, Ltd. 2000-2022. All rights reserved.
*/
```

Release notes for DiKTat 1.0.1 mention a PR that fixes the copyrights rule:
