[Rules migration] Allow partial RuleResponse object to be passed to…

… `RuleOverviewTab` (#204318)

## Summary

These changes allow `Partial<RuleResponse>` to be used as a parameter
for `RuleOverviewTab` component.

We re-use this component for "SIEM Migrations" feature to display
translated state of the rule which has just a few fields that represent
the `RuleResponse` object. The set of fields used in `RuleMigration`
object is a minimum set of fields enough for the rule creation.

Right now, `RuleOverviewTab` component requires the complete
`RuleResponse` object to be passed even though internally each section
(`RuleAboutSection`, `RuleDefinitionSection`, `RuleScheduleSection` and
`RuleSetupGuideSection`) of the rule's overview expects
`Partial<RuleResponse>`. To be able to use this component we force type
casting at the moment and would like to get rid of it.
