[apex] ApexAssertionsShouldIncludeMessage and ApexUnitTestClassShouldHaveAsserts: support new Assert class (introduced with Apex v56.0)

[tprouvot]

Affects PMD Version:
all

Rules:

• ApexAssertionsShouldIncludeMessage
• ApexUnitTestClassShouldHaveAsserts

Description:
With the Winter 23' release, a new class can be used to perform assertion in test class.
We have to add the new methods to existing rule to avoid false positive when this class will be used.

Apex class Assert
Code Sample demonstrating the issue:

@isTest
public with sharing class Test {

	@isTest
	public static void testAssert(){
		String sub = 'abcde'.substring(2);
		Assert.areEqual('cde', sub, 'Expected characters after first two');
	}
}

Expected outcome:

PMD reports a violation at line ..., but that's wrong. That's a false positive.

Running PMD through: [VS Code]
