Change storefront tab styling	NEXT-10255

Storefront

Changed in src/Storefront/Resources/app/storefront/src/scss/skin/shopware/component/_tab-menu.scss
- Removed background color of .nav-link:active and .nav-link:hover in _tab-menu.scss to make a transparent background color for storefront tab.
- Added background color to .nav-link:hover to set tab hover background color 20% darker compared to background color of body.
