Admonition added to warn about using latest MU

[0rnela]

Description

To set expectations if a customer report a bug in an old MU version, as in such case, we request customers to update to the latest MU version of that product.

To address that, the existing copy was reshuffled and tidied up, and the new copy added to the existing admonition.

I revoked my approval. The exact statement is to be clarified with the product owner. The statement must fit for all clients. The most important thing (IMO) is to say that the

client is supported by the organization that supplies the operating system

@admd can you please confirm if the text in the admonition can be merged? The rest of the changes in this PR are just simplification and cleanup of the already existing text.

When reporting an issue in an old version, customers need to ensure that the client is running the latest maintenance update version of that product.

wording is ok for me. but sooner or later we must clarify what "support" means where it occurs. Also see my proposal: https://github.com/SUSE/spacewalk/issues/18593 --but I cannot do this.
