Agentic workflows add main repo constrain

[marcelofukumoto]

Summary

Fixes #17489

Occurred changes and/or fixed issues

• Added 2 changes to avoid problems on the agentic workflow
  • Added the integrity to none for now until we can figure out about the NOTEs added (it was initially working with that config)
  • Added a prestep to stop fork execution
• Updated the version as well

Technical notes summary

• For now there is no way to remove those PR messages, so it is going to mark them, to avoid that, the best is to put integrity none for now. The flows were created with that and the config is not enough currently to allow more configuration.
• The documentation says fork will not execute it, but it is executing right now, so to avoid it added a pre step
