add a preview note for all non-bootstrap commands

[aryan9600]

add the following note to all non-GA commands as described in #3274:

⚠️ Please note that this command (group) is in preview and under development.
While we try our best to not introduce breaking changes, they may occur when
we adapt to new features and/or find better ways to facilitate what it does.

fixes #3739

@aryan9600 please rebase with the release-v2.0.0-rc.1

[stefanprodan]

@aryan9600 the warning must be displayed only on commands that don't deal with v1 APIs. As listed here: #3274

Maybe undo such changes to keep the diff focused on non-GA commands only?
Or convert all the long message of every command to use the same syntax.

Just wanted to see how others feel about the idea I've been thinking about while going though the changes.
For commands that have some subcommands that are GA, how about not marking the parent command as preview?
For example, flux create and flux create source need not be marked as preview, but only the specific subcommands, like flux create source bucket can be marked as preview, wherever relevant. That way, it doesn't give the impression that the whole create or create source command group is in preview.
I think this would make the preview marker more granular instead of a catch-all like implementation. In relation to a previous discussion about marking only git secret creation GA, I think this would make it more apt to selectively mark other secret types as preview. Removing the oddness of overall command group being in preview but only one small part of it being GA.

Yes, I agree. Seeing the warning on flux create is strange, given that flux create source git doesn't show it. Same is true for other groups. And then we can remove the (group) from the message as well and make the warning more specific.

Yes +1
