fix: Unlocalize ids to avoid js errors for ids greater than 999

[fsbraun]

Description

On sites that have more than 1000 pages, when rendering admin/cms/page/tree/menu.html all the page ids and node ids are rendered localized, with e.g. commas or apostrophes for thousands separators.

When we then expand a node, those node's data-id are picked up and stored in local storage under cms_cookie in their localized form.

This has been fixed in 3.11 but remains open for the develop-4 branch.
