Add disclaimer banner to the documentation of the components which are not updated for a long time

[luixxiul]

Is your feature request related to a problem? Please describe.

Some components of the playbook have been officially declared as unmaintained/deprecated, while others apparently seem to have been abandoned for years after the playbook was born and components actively developed at that time were added, such as ma1sd.

Describe the solution you'd like

I think it should be no problem to keep those services in the playbook as long as they work properly for the most cases, but a friendly disclaimer on the documentation that the upstream project seemingly has been inactive for a certain period of time (a year, for example?) should help us to figure out where to look at when an unknown error occurs.

As it is possible that the component is so stable that it has not received an update for a long time, such a disclaimer would be proper for the inactive project which has received a bug report, which is the case for ma1sd: #2663

Describe alternatives you've considered
