fix(plugin-market): restore missing "页面"(Page) component filter option

The market component-filter list on this branch was a diverged rewrite that
dropped the Page component kind master had added. The i18n key
(market.componentName.Page) already existed; re-add the Page entry to the
componentOptions list so plugins providing Page components can be filtered.
