Doc: NuxtImg multiple formats

[Yves852]

Tested the format prop like the following, switching order and testing with typos. Image type (not extension) seems to change/fallback accordingly.

<NuxtImg format="webp,jpg" src="/nuxt-icon.png" ... />

Could the use of multiple format be explained in the doc for NuxtImg?

Is it advised to use multiple formats with NuxtImg comparing to NuxtPicture?
If not could it have a warn in the doc against this practice?

Current doc: https://image.nuxt.com/usage/nuxt-img#format

Thanks.

In my experience, I usually set only one format for component NuxtImg (like format='avif'). I looked how Next Img does that and they seem to only support setting format in the global configuration not inline component.

What would be your opinion @danielroe? Should we only allow to set multiple formats throght the global config and only allow to set one format in NuxtImg? Or should we allow for this fallback?

If it works already, maybe it would be good to just document it and support it as per comment of @Yves852 ? :)

When used with provider it will prevent the image displaying, probably due to the whole string being used to request a unique format which is incorrect.

<NuxtImg format="webp,jpg" provider="directus" src="/nuxt-icon.png" ... />

Maybe I should open a feature request to handle multiple format (the last being fallback), right now waiting to see if this issue get an update first.
