Shouldn't we use the new kestra.plugins.configuration property to override default values of the Schedule `recoverMissedSchedules` property? sure, might be more intuitive that way

I believe someone initially suggested `server` by assuming this is meant as Scheduler property 

just to confirm, would this be then like so?

```yaml
kestra:
  plugins:
    configurations:
      - type: io.kestra.core.models.triggers.types.Schedule
        values:
          recoverMissedSchedules: LAST | NONE | ALL # ⚡️ new!
```
 > just to confirm, would this be then like so?

Yes it will.
@loicmathieu shouldn't this be `recoverMissedSchedules: ALL`? (without hyphens)
Allow disabling system backfills on crash
1. deprecate `backfill` property in the Schedule trigger source code
2. add `recoverMissedSchedules` Enum property set by default to ALL (by default backfilling all missed scheduled executions)
3. add a global configuration on the instance as shown below (best if we use the same naming as on the property for easy understanding) -- this configuration is taken into account if not explicitly set in the trigger definition
    
syntax for the Schedule property:

```yaml
triggers:
  - id: schedule
    type: io.kestra.core.models.triggers.types.Schedule
    cron: "*/15 * * * *"
    recoverMissedSchedules: LAST | NONE | ALL # ⚡️ new! 
    backfill: # ❌ show deprecation when this property is used 
```

syntax for the global configuration:
```yaml
kestra:
  plugins:
    configurations:
      - type: io.kestra.core.models.triggers.types.Schedule
        values:
          recoverMissedSchedules: LAST | NONE | ALL # ⚡️ new!
