import stylesheets to cypress test files

[reachaadrika]

Reason/Context

• Currently while writing the cypress tests css is not imported and rendered on the test window .
• While writing tests , it is important for css to be rendered on the test window , since it becomes easier to review and check the UI classes if the classes are visible and even the specific colors are rendered .

Description

• Import the global css file into the main cypress component file
• This is not a breaking change
