various: use of deprecated url.parse

### Describe the bug

I noticed deprecation warnings for url.parse on node 24.13.1. The warning was specifically from @aws-cdk/cloud-assembly-schema and I'm not on the latest version of that, but there's a handful of search results for url.parse in the aws-cdk github.

```
(node:1058478) [DEP0169] DeprecationWarning: `url.parse()` behavior is not standardized and prone to errors that have security implications. Use the WHATWG URL API instead. CVEs are not issued for `url.parse()` vulnerabilities.

at Object.urlResolve [as resolve] (node:url:725:10)
at Validator.validate (.../@aws-cdk/cloud-assembly-schema/node_modules/jsonschema/lib/validator.js:118:21)

Run `cdk` with Node.js 24.13.1 to reproduce the warning, then inspect the stack entry at `@aws-cdk/cloud-assembly-schema/node_modules/jsonschema/lib/validator.js` and the repository's `url.parse` search results. Confirm which occurrences are responsible and verify that the CDK command completes without the deprecation warning.
