Drop support for PHPUnit < 7.5 [1]

Adjust CI, README and `composer.json` for the drop of support for PHPUnit < 7.5.0. The 7.5.0 version is a deliberate choice to allow for dropping all PHPUnit 7.x related polyfills.

 This library is set up to allow for creating PHPUnit cross-version compatible tests by offering a number of polyfills for functionality which was introduced, split up or renamed in PHPUnit.
 
-### Write your tests for PHPUnit 11.x and run them on PHPUnit 6.4 - 11.x
+### Write your tests for PHPUnit 11.x and run them on PHPUnit 7.5 - 11.x
 
 The polyfills have been setup to allow tests to be _forward_-compatible. What that means is, that your tests can use the assertions supported by the _latest_ PHPUnit version, even when running on older PHPUnit versions.
