Update DJS current scenario (remove unneeded steps and breakdown current scenario)

[Mai-Saad]

• using e2e v 1.1.0 , we can see here https://github.com/wp-media/wp-rocket-e2e/blob/develop/src/features/delay-js.feature#L17 we enable mobile cache and separate mobile cache, however, those are enabled by default since WPR 3.16+
• The current scenario can be broken down into multiple scenarios i.e

1. Validate that no VR , no console error with different themes on desktop
2. Validate that no VR, no console error with different themes on mobile including mobile menu
3. Validate that no console error with WPML when switch language
4. Validate that links are clickable in footer with different themes

=> let's take the opportunity of updating tests here to add more highly used themes
=> to be discussed: some themes probably need to enable one click exclusion or we will have VR, may be we need to enable theme one click exclusion whenever it's there
