feat(ops/terraform): add trigger to deploy-nixos, remove target_name r/5872
This allows passing in custom triggers to trigger a (re)deploy.

For example, a caller can put an AWS instance ID into the triggers to
cause a redeploy whenever the instance ID has changed.

The `target_name` terraform variable was doing something similar, but
`triggers` is more generic, allowing multiple triggers, without having
to stringify them.

We also don't need to trigger on the attrpath - it can be changed, and
as long as it still evaluates to the same
`data.external.nixos_system.result.drv` (which is checked on every
plan), no redeploy needs to be made.
