Add note for apt installations

[Tostti]

Description

This PR adds a note to the upgrade central components section, for apt installations noting that if the opensearch_dashboards.yml was modified, the system will ask to either keep the modified version or replace it with the updated one, meaning that the user will have to manually add the changes later.

LGTM!

Added a commit with a new suggestion which I can easily revert. And what about the yum upgrade? Should we remove the file before upgrading to force updating the file?

I think that it should. In that case we'll be sure that the file is completely replaced
