Undo link color on success notification

[jeroenvdmeer]

What you were expecting:
Using the new "success" notification type, the notification is turned green. The undo link is still the primary color of the theme, which by default is blue. I would expect the link color to match the green notification color, such as green 900 (#1b5e20).

What happened instead:

Steps to reproduce:
notify("resources.employee.updated", "success", {}, true)

Environment

• React-admin version: 3.14.3
• React version: 17.0.2
• Browser: Chrome Version 90.0.4430.72 (Official Build) (64-bit)
