Add hovering for descriptions of disabled rules #disable-next-line

It would be great that after we auto complete the rule ids being used to disable a rule on a next line, the user will be able to hover over that rule such as `no-harcoded-location` and get a full description of what it means

The issue concerns autocomplete for rule IDs used with #disable-next-line and hover descriptions in the editor. Start by locating the existing completion behavior for those rule IDs. Done means hovering over a rule such as `no-hardcoded-location` displays its full description.
