Instance creation w/ bootscript is broken

[NoSuchCommand]

Description:

Instance creation allows the bootscript-id= parameter to have it boot using a bootscript. Despite the information being recorded as part of the instance's metadata, the bootscript seems to be ignored.

How to reproduce:

1. Create an instance with bootscript-id= pointing to a bootscript of the right zone
2. Wait for the instance to boot
3. Connect using SSH
4. Compare the running kernel version to the bootscript kernel version
5. Inspect the instance's boot type

Command attempted

$ scw instance server create image=ubuntu_focal bootscript-id=7af80bed-c7b5-4fdc-8973-9013712895bb
$ scw instance server wait <ID>
$ scw instance server ssh <ID> command='uname -r'
$ scw instance server get <ID> | grep boot-type
boot-type                local

Expected Behavior

The guest's kernel version should match the bootscript's.
The instance's boot type should be bootscript.

Actual Behavior

The instance's boot type is local.
Hence the running kernel is the one from the installed system.
