languages: Fix local path of JSON and YAML schemas (#44794)

Closes #30938

Release Notes:

- Fixed: Unable to load relative path JSON schema for YAML validation
(#30938)


This patch follows the vscode LSP client logic, see
[`jsonClient.ts`](https://github.com/microsoft/vscode/blob/cee904f80cc6d15f22c850482789e06b1f536e72/extensions/json-language-features/client/src/jsonClient.ts#L768-L770).
The `url` of the JSON schemas settings and the YAML schemas settings
should be resolved to an absolute path in the LSP client when it is
submitted to the server.
