fix(ssr): render hidden correctly

[chirokas]

Add support for hidden="until-found"

This PR fixes the issue where Vue treats the hidden attribute as a boolean, causing "until-found" to be incorrectly rendered.

core/packages/shared/src/domAttrConfig.ts

Lines 21 to 23 in f6e84af

	export const isBooleanAttr: (key: string) => boolean = /*@__PURE__*/ makeMap(
	specialBooleanAttrs +
	`,async,autofocus,autoplay,controls,default,defer,disabled,hidden,` +
