Improve wizard and lists

[TheKinrar]

• The scoring system of the simple list is confusing as it allows instances that do not match your exact criteria. Maybe keep this as an option, but more explicitly.
• Keeping simple list is fine I think, but it needs to be more useful. Adding more information to it could be fine.
• Advanced list needs to be improved so that the legacy one can be removed.
• Maybe rename advanced list to "table view" or something like that and merge it with the simple one. It's not that advanced as it actually show less information (for example, nowhere to put the description / rules)
• Better moderation filters (see Moderation filter removed #130)
• Software filter: the wizard should list only Mastodon instances by default and provide the option to look for other types, especially if Support other fediverse software #51 is fully implemented at some point
