[v10.1.x] Unified Alerting: Set max_attempts to 1 by default (#79102)

Unified Alerting: Set `max_attempts` to 1 by default (#79095)

* Unified Alerting: Set `max_attempts` to 1 by default

The retry logic for unified alerting has been broken as far as v9.4.x, rather than fixing it in one go and causing a headache to our users with rules putting extra load on their datasources - I think a better approach is to simply set 1 as a default and then let our users change it.

I see two cons with this approach:

- Configuration for legacy to unified alerting cannot be ported over automatically, users will have to manually set `max_attempts` to 3 when migrating.
- Users expecting to get any sort of retrying (as with legacy alerting) will not have it out of the box and will have to manually edit the configuration.

Sets a maximum number of times we'll attempt to evaluate an alert rule before giving up on that evaluation. The default value is `3`. This option has a [legacy version in the alerting section]({{< relref "#max_attempts-1" >}}) that takes precedence.
