Background

Currently, in the MAPI to CAPI conversion we hard code the ignition version.
This was a required field until CAPA > v2.9 / OCPCLOUD-2719 was implemented

After bumping to a supported version, we should stop setting an ignition version during MAPI to CAPI conversion.

Steps

• Ensure CAPA was bumped to > 2.9.0
• Drop version handling (hardcoded to `3.4`)

Stakeholders

• Cluster Infra

Definition of Done

• Cluster CAPI Operator (CCO) does not set ignition version anymore on AWSMachine's or AWSMachineTemplates

• <Add docs requirements for this card>
