remove unnecessary semicolon which breaks zsh on mac

[craigbox]

zsh, in many default configurations, escapes special characters on paste. The ; in the Gateway API example is replaced with \; which causes the command to fail.

As it's not a load-bearing semi-colon, lets just remove it.

Fixes #16162

[craigbox]

you're kidding me. it is a load bearing semi-colon?

[craigbox]

Now we don't use kustomize should I just nuke the braces?

[kfaseela]

saw the lint failure only after approving :D

[craigbox]

note to self, make Faseela an approver for Ukranian too
