The schema validation does detect the following wrong schema as valid:

#cloud-config
groups:
  - 3.14

Steps to reproduce:

cat <<EOF > /tmp/user-data
#cloud-config
groups:
  - 3.14
EOF

lxc launch ubuntu-daily:jammy gg --config=user.user-data="$(cat /tmp/user-data)"
$ lxc exec gg -- cloud-init status --wait
..............
status: error

$ lxc exec gg -- grep -ni "error" /var/log/cloud-init.log
412:    raise TypeError(
413:TypeError: Unknown group name type float
440:    raise TypeError(
441:TypeError: Unknown group name type float

$ lxc exec gg -- cloud-init schema --system
Valid cloud-config: system userdata

$ lxc exec gg -- echo $?
0

The schema validation should detect this schema as invalid.
