GHA ubuntu.yml: Upgrade LIMA_VERSION to 1.2.1

This requires a fix to make sure additional_gestagents is really set to
`true` (which hardcodes it to true even though not needed for x86_64)

Also set `LIMA_SSH_PORT_FORWARDER=true` and `LIMA_USERNET_RESOLVE_IP_ADDRESS_TIMEOUT=5`
on the `limactl` command line

Note: This commit also adds `LIMA_SSH_PORT_FORWARDER` and `LIMA_USERNET_RESOLVE_IP_ADDRESS_TIMEOUT`
to the `limactl start` command in `setup-nixos.sh`.
