chore: update workflowNodeVersion to lts/* (#636)

Currently `upgrade-configuration` workflows are failing for `cdk8s-cli`: https://github.com/cdk8s-team/cdk8s-cli/actions/runs/6998871953.

This is due to us editing the workflow file and adding `lts/*` based on step number. This step number changes if we have `workflow bootstrap steps`, which would [precede](https://github.com/projen/projen/blob/da981a3e2651344ef2cc342708e67c75c0433c02/src/javascript/node-project.ts#L974C9-L974C9) node step. This results in us editing the file at the incorrect spot and lead to an incorrect workflow yaml file. 

Instead of editing the workflow file and relying on the step number to be correct, I am instead adding this to `workflowNodeVersion` property of projen projects.
