ci(aks+eks): bootstrap juju controller with agent version 3.5.0

[orfeas-k]

Context

#921 is causing issues when deploying some charms; we need to add the workaround suggested there.

What needs to get done

Edit the deploy-to-eks and deploy-to-aks workflows to bootstrap the juju controller with agent 3.5.0 to avoid the issue.

Definition of Done

The juju controller that runs in those workflows is bootstrapped with agent 3.5.0 and the error is not present on the CI anymore.
