[Cloud Security] Update the minimum supported Kibana version for the upcoming release

• https://github.com/elastic/security-team/issues/13130

Overview
This PR removes the transform commit from the current 2.0.0 version of the Cloud Security integration to ensure compatibility with Kibana version ^8.19. The goal is to address the issue of duplicated findings that occurs when the transform is present in environments running Kibana 8.19.

Background

• Integration 2.0.0 was initially released with changes intended for Kibana 9.1, including a new transform.
• When installed on Kibana 8.19, this caused duplicated findings due to both the old and new transforms running simultaneously.
• To resolve this, we are removing the transform commit from 2.0.0, making it stable and compatible for Kibana ^8.19 deployments.

Changes

• Reverts the transform-related changes that were included in 2.0.0.
• Ensures that the integration will not introduce duplicated findings for users on Kibana 8.19.
• Maintains all other features and fixes intended for 2.0.0, except for the transform.

Impact

• Kibana ^8.19 users will receive a version of the integration that is free from duplicated findings and compatible with their stack.
  • The transform changes will be reintroduced in a future integration version (3.0.0) targeting Kibana 9.1+.

Note: A follow-up PR will introduce the transform changes in integration version 3.0.0 for Kibana ^9.1 and above.
