fix(action-sheet): remove the height shift on press

[brandyscarney]

Short description of what this resolves:

This changes the border into a linear gradient background image which allows us to avoid the height decrease on press and have the same border as the background color when pressed.

• changes border color to match native
• removes the negative margin shift on press
• makes the cancel button #ffffff by default
• combines e2e tests back to basic

Fixes #16790
References #16715

This should be good to merge if the build passes + screenshot looks good. It has been approved by Ben. We may want to iterate on the translucency in the future but it is pretty close to native.

Update: after discussing with Adam we discovered the compareScreenshot was stopping the tests when the expect failed. So we are moving the tests out to where there is only one compare per test. This PR needs to be updated for Action Sheet still, and then we can look at the remaining ones that have multiple compares separately.
