Add a separate page how to get assistance

[sboldyreva]

Currently, it's unclear how users can get any assistance. Having a separate page dedicated to this that is easy to spot for users could be a good idea. For everyone's convenience, it may be worth mentioning all the discussion spaces and some recommendations.

Also may help with the https://github.com/AlmaLinux/wiki/issues/341

The pr to collaborate - https://github.com/AlmaLinux/wiki/pull/361
