auro-lockup: Alias oneworld due to Svelete 5 issues

[mspears-alaska]

Is your feature request related to a problem? Please describe.

In Svelte 5, attributes starting with on are shadowed (see my issue on the svelte repo here), this means the oneworld property isn't usable without a workaround.

Describe the solution you'd like

Can we get an aliased attribute like hasOneworld?

Describe alternatives you've considered

We recently found out you can just do the workaround below, but it's less than ideal.

{@html "<auro-lockup oneworld></auro-lockup>"}

So far no other workaround has been suggested on the svelte issue.

Additional context

This also affects other components like <auro-icon> and it's ondark attribute.
