 Follow up to #61627.

 In [58813] the helper function `wp_get_wp_version()` was introduced as a
 way of getting the WordPress version without relying on the `$wp_version`
 global. This is to bypass bugs introduced by plugins modifying the value
 for reasons of security through obscurity.

 As `is_wp_version_compatible()` currently uses the `$wp_version` global,
 such a plugin would affect and break the function. Now a helper function
 exists for getting the unmodified value it would be good to use it.

 Test suite considerations: The tests for `is_wp_version_compatible()`
 currently modify the value of the WordPress version in order to test that
 the function works as expected with alpha, beta, RC and WordPress-Develop.
 The code will need to be written in such a way that this can continue to
 be tested.
