Refs #37010 - Ensure correct yaml for netplan

[bastian-src]

The changes in #9967 introduce the save navigation operator. Unfortunately, the corresponding snippet relies on the passed arguments being true/false instead of nil.

@ekohl should we add a safety check to the preseed_netplan_generic_interface that turns nil into false or revert the save navigator change in this snippet?

Or am I overseeing something here?

[bastian-src]

Katello tests seem unrelated AFAIK.

@sbernhard you're right with your comments. I've changed the corresponding lines.

LGTM

[ekohl]

@sbernhard you can only merge with Refs if you cherry pick it to the stable branch. Otherwise you'll end up with a missing commit.

Apologies for missing this. I'd actually say the easier fix is to enforce a boolean in preseed_netplan_generic_interface.erb. I think #10102 is that.
