on the UI side we probably don't want to allow other html.

# What this PR does
Web templater had a bug with link substitutions: it replaced every link
with 'oncallsubstitutedlink{link_idx}', and then replaced them back.
But if we have more than 10 links in the message, there
would be replacements like 'oncallsubstitutedlink10', which will be
partially replaced by match from 'oncallsubstitutedlink1', yielding
incorrect links in the resulting message. This fixes this behaviour.

# What this PR does
This is a follow up to #2502 which started to remove logic to
"archiving" alert groups. This PR:
- removes all references to `AlertGroup.is_archived` and marks the
column as deprecated. We will remove it in the next release
- removes the `AlertGroup.unarchived_objects` `Manager`
- renames the `AlertGroup.all_objects` `Manager` to `AlertGroup.objects`
