We add a new field delete_at in the channels template.
This field is then searched in the SearchChannels function.
Also added tests to verify that archived channels are searched
properly, and also indexed correctly.
https://mattermost.atlassian.net/browse/MM-62295
```release-note
- Now archived channels are searchable with ES/OS if TeamSettings.ExperimentalViewArchivedChannels is enabled.
- If there are old channels which were archived before a bulk index was run, users would need to purge indexes, and do bulk index again. Because those old archived channels are removed from the index when a bulk index is run.

It was a good decision in hindsight to keep the public module as 0.x
because this would have been a breaking change again.
https://mattermost.atlassian.net/browse/MM-53032
```release-note
Changed the Go module path from github.com/mattermost/mattermost-server/server/v8 to github.com/mattermost/mattermost/server/v8.
For the public facing module, it's path is also changed from github.com/mattermost/mattermost-server/server/public to github.com/mattermost/mattermost/server/public
```
Mockery started to throw errors like "Unexpected package creation during export data loading".
This was consistently reproducible locally and on upgrade, it has gone away.
```release-note
NONE
```
