This PR essentially reverts https://github.com/PowerShell/PowerShell/pull/3331, which updated all W3C URIs in the `.resx` files from `http` to `https`.
That change turned out to be wrong. Those W3C URIs are namespace identifiers, not fetchable URLs -- they must be byte‑exact. Changing them to use `https` corrupted them, and thus `ManagedParser` in the localization pipeline can't recognize the schema, which resulted in the `BL1024 "child table to itself"` error.
- This PR makes pure, mechanical 2-line substitution in every `.resx` file: `https://www.w3.org → http://www.w3.org`.
- The `ClipboardResources.resx` was using Schema version 1.3, and it's changed to version 2.0 as the rest `.resx` files in this PR.
