Fix build failures caused by the New Year

[lutovich]

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. It is not entirely clear why the tests started failing, but the error behavior 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: https://github.com/analysis-dev/diktat/releases/tag/v1.0.1

Fix DiKTat tests after a version bump

FIRST_COMMENT_NO_SPACES rule renamed to FIRST_COMMENT_NO_BLANK_LINE in saveourtool/diktat#759.

Update explicit version to 1.0.1.

Remove copyright header rules because we do not want DiKTat tests to fail every New Year.

Fix licence header test

Compute the current year instead of using a fixed year 2021. This test started failing after the New Year.

Fix a few more DiKTat test failures

Use the newest DiKTat version. Change expected messages. They do not look right - probably a bug in DiKTat.

Example failure with DikTat 0.4.0:

The error changes when I add a dummy copyright header:

SEVERE: Step 'diktat' found problem in 'src/main/kotlin/Main.kt':
There are 1 unfixed errors:
Error on line: 1, column: 1 cannot be fixed automatically
[WRONG_COPYRIGHT_YEAR] year defined in copyright and current year are different: year should be 2022
java.lang.AssertionError: There are 1 unfixed errors:

Amazing, thanks so much! I tweaked changelog entries a bit and I'll merge a whole bunch of PRs in the next hour or two :)

@nedtwigg @lutovich thank you guys!
Btw, this issue with copyright will never appear again after saveourtool/diktat#1151 saveourtool/diktat#1154

Now the current year will properly be calculated automatically
