new system integration options broke shell completions

[xdBronch]

moved from ziglang/zig#18866

Steps to Reproduce and Observed Behavior

in a zig project with no system integrations options ask for shell completions with the prompt zig build -
rather than completing options like before it will print out

_arguments:comparguments:327: invalid argument: (none)[-]:
_arguments:comparguments:327: invalid argument: (none)[-]:
_arguments:comparguments:327: invalid argument: (none)[-]:

this is due to the new section from ziglang/zig#18778

Available System Integrations:                Enabled:
(none)                                        -

if there are any system integration options the completions will work again

this is on zsh, i dont have shell completions setup for anything else so im not sure if it happens for those, sorry.

Expected Behavior

give completions for build options

[xdBronch]

the completions in general need to be updated quite a bit, can they be autogenerated? im not familiar with sed and it seems extremely tedious doing any of this manually

I'm sure it's possible to automate but I find it much easier to just do it manually once or twice a year.

And zig build - completions have never worked that well to begin with #3
