Add size xs to LoadingIndicator or make customizable

[oskar-oss]

Problem or use case

I need a smaller size of the loading indicator which fits in an input component and xs would be great if it could be passed. Alternatively if it would accept className as prop to override styling.

Proposed solution

xs: {
    root: "gap-4",
    label: "text-xs font-normal",
    spinner: "size-4",
},

to loading-indicator.tsx together with added xs to Props

Alternatives considered

accept and pass className as prop.
