Clarity load time for cloud environment

[yeekangc]

Sometimes, it may take more than a minute to start the environment. Update the provided information/instruction to indicate that it may take more than a minute?

@Emily-Jiang obvsered this too:
it takes more than a minute to load up - I am wondering whether we can say it will take a couple of minutes instead of saying one minute

@yeekangc is it ok to add the message on the landing pages before/beside/below the Access cloud-hosted guide button?
