How toTurn on Caps Lock on Cypress

If you're testing a feature that depends on Caps Lock to be on, e.g. detect Caps Lock and warn on password inputs. You can test this works on Cypress using the following snippet.

cy.findByLabelText("Password").trigger("keydown", {
  key: "CapsLock",
  getModifierState: (key) => key === "CapsLock",
});

The findByLabelText function depends on Cypress Testing Library, use it to find the input elemnt, then call trigger with the keydown event, pass the key and in getModifierState return true if the key is CapsLock so it's activated.
