* Prefixes live event tags according to the conventions used by `defineLive().sanityFetch()`

*
* @example
* ```tsx
* import {updateTag} from 'next/cache'
* import {parseTags} from 'next-sanity/live'
* import {SanityLive} from '#sanity/live
*
* <SanityLive
*   action={async (event, context) => {
*     'use server'
*
*     for (const tag of parseTags(event.tags, context)) {
*       updateTag(tag)
*     }
*   }}
* />
