[Error] Multiple init hooks in a distrobox assemble break the creation

[Nitrousoxide]

Please, before opening a bug:

Describe the bug
Multiple init hooks will break a distrobox assemble operation.

To Reproduce
Create an assemble file with at least two init hooks.

Here is an example file:

[Boxkit-Assemble]
image=quay.io/toolbx-images/alpine-toolbox:edge
init=false
init_hooks="apk update && apk upgrade"
init_hooks="ln -fs /usr/bin/distrobox-host-exec /usr/local/bin/podman"
nvidia=false
pull=true
root=false
replace=true
start_now=true

Commenting out either of those init hooks and leaving the other in operation will work fine.

Moving the ln command into the first init hook just seperated by &&'s will work as well

[Boxkit-Assemble]
image=quay.io/toolbx-images/alpine-toolbox:edge
init=false
init_hooks="apk update && apk upgrade && ln -fs /usr/bin/distrobox-host-exec /usr/local/bin/podman"
#init_hooks="ln -fs /usr/bin/distrobox-host-exec /usr/local/bin/podman"
nvidia=false
pull=true
root=false
replace=true
start_now=true

Expected behavior
Both inits should be run with && between them or run as separate lines. The ability to use multiple init lines makes the file much more readable.

Hi @Nitrousoxide

this was missing in the documentation, each hook needs to end with ; in order to execute them one by one
