Add a note to clarify that the EE_LICENSE environment variable needs to be exported before running EE specific tests
This commit adds a short note to the 'What Tests Can Be Run' page, to clarify that the EE_LICENSE environment variable should be set before running EE specific tests.
If this is not set, the tests fail with capybara ElementNotFound errors.
