Fix issue #987

[github-actions]

This PR touches files which potentially affect the outcome of the tests of an exercise. This will cause all students' solutions to affected exercises to be re-tested.

If this PR does not affect the result of the test (or, for example, adds an edge case that is not worth rerunning all tests for), please add the following to the merge-commit message which will stops student's tests from re-running. Please copy-paste to avoid typos.

This is a real special case. The example should not be in the TestDox.

Suggested change

	*/
	#[TestDox('Random key cipher -> Is reversible. I.e., if you apply decode in a encoded result, you must see the same plaintext encode parameter as a result of the decode method')]
	public function testRandomKeyCipherReversible(): void
	/**

	public function testRandomKeyCipherReversible(): void

Please go through all DocBlocks and fix the indentation. 4 spaces on the comment starting line, then 5 spaces until the comment ends. That's the rule. And no dot after the UUID.

Please adjust the method names to match the TestDox sentence.

Suggested change

	public function testRandomKeyCipherEncode(): void
	public function testRandomKeyCipherCanEncode(): void

Again, it's better to skip the example here:

Suggested change

	#[TestDox('Substitution cipher -> Is reversible. I.e., if you apply decode in a encoded result, you must see the same plaintext encode parameter as a result of the decode method')]
	#[TestDox('Substitution cipher -> Is reversible')]
