Suppress missing template warning

[rak-phillip]

Summary

This suppresses the missing template warning by using a render function to generate a valid vnode.

Fixes #16236

Occurred changes and/or fixed issues

• Suppress missing template warning

Technical notes summary

The render function with a valid v-node technically renders a div. This shouldn't have an effect on the rendered output of the component since the beforeCreate() hook acts as a router guard to update the route before anything renders to the page.

I considered moving the entirety of the logic into shell/config/router/routes.js, but the reliance on the store has carries more risk for regression.

Areas or cases that should be tested

Navigate to the settings page. Warning should be suppressed and the page renders as expected.

Areas which could experience regressions

This could technically render a page with an empty div in the setting page if the routing fails, but this would not be any different from the existing behavior.
