Get placeholder error on del/1 function

[itchyny]

❯ jq -n '{x:[1]} | del(.x[0],.x)'
{}

❯ xq -n '{x:[1]} | del(.x[0],.x)'
Error: IndexOnNonIndexable("placeholder")

More cases to test:

$ jq -n '{x:[1]} | del(.x.y, .x[0], .x)'
jq: error (at <unknown>): Cannot index array with string "y"
[2]    563536 exit 5     jq -n '{x:[1]} | del(.x.y, .x[0], .x)'
$ jq -n '{x:[1]} | del(.x[0], .x.y, .x)'
jq: error (at <unknown>): Cannot index array with string "y"
[2]    563544 exit 5     jq -n '{x:[1]} | del(.x[0], .x.y, .x)'

and nested slices.

@itchyny @MiSawa just want to say thanks for interesting issues and fixes, learning a lot about jq. Would like to learn more rust so maybe xq could be a good motivation!
