chore(ci): swap to new aws account for rke/eks tests

[joelmccoy]

Description

Swaps over the eks/rke2 tests to the new AWS commercial account. Points the CI to use the new vpc, state bucket, state lock table provisioned in that account. The base infra is defined in this repo and managed with our spacelift integration.

Additionally for the rke2 workflow, the terraform data filter needs to provide the new owning aws account id (since the AMIs are published in a different account than which the CI runs in). The following secrets will need to be updated/created before this will work (I can provide these out of band and then rerun the test CI):

• PERMISSIONS_BOUNDARY_ARN
• PERMISSIONS_BOUNDARY_NAME
• AWS_COMMERCIAL_ROLE_TO_ASSUME
• UDS_IMAGES_AWS_ACCOUNT_ID
