Update the event-generator to reflect the recent ruleset split (stable, incubating, sandbox)

[leogr]

Motivation

Because of the Rules Maturity Framework proposal.

Feature

• Reflect rules' changes
• Implement a way to select action groups stable, incubating, sandbox
• Only enable stable ones by default

Alternatives

No compelling alternatives.

Additional context

I assume we don't want any more of those rules which are now deprecated.

• Only enable stable ones by default

This has been addressed by https://github.com/falcosecurity/event-generator/pull/90

• Implement a way to select action groups stable, incubating, sandbox

Likely, the best way to implement this is to add tags to the actions (similarly to rules tags) and implement a feature that allows filtering by tags. cc @FedeDP wdyt?

I agree, seems like the simplest solution.
