Importing module on filesystem from data URL throws `TypeError: Invalid URL` / `ERR_UNSUPPORTED_RESOLVE_REQUEST: Invalid relative URL or base scheme is not hierarchical.`

### Version v20.11.1 ### Platform Linux devbox.home.arpa 6.1.0-16-amd64 #1 SMP PREEMPT_DYNAMIC Debian 6.1.67-1 (2023-12-12) x86_64 GNU/Linux ### Subsystem _No response_ ### What steps will reproduce the bug? Creating an `index.mjs` file with the following contents and running it with `node index.mjs` causes nodejs to be unable to resolve the `foo` module when running in base-64 land. ```js import fsp from 'fs/promises'; // create `foo` module await fsp.mkdir('./node_modules/foo', { recursive: true }); await fsp.writeFile( './node_modules/foo/package.json', JSON.stringify({ name: 'foo', exports: { '.': './index.mjs', }, }) ); // build base64 url just importing `foo` const importName = `foo`; const unencoded = `await import("${importName}")`; const encoded = Buffer.from(unencoded).toString('base64'); const url = `data:text/javascript;base64,${encoded}`; // import that base 64 url await import(url); ``` This seems to be because to resolve `foo` we try to load `package.json`'s, but it seems like we're trying to do it *from* the data URL, which can't work. ### How often does it reproduce? Is there a required condition? You should run this code somewhere where it's safe to create a new `node_modules`. Running the code always produces the same result on macOS and Linux. Untested on Windows. ### What is the expected behavior? Why is that the expected behavior? Either: - nodejs should error with a clear description of the problem, rather than throw an internal error from URL - (or) nodejs should allow importing from the data URL by using the context of the base64 module's parent for imports called from the base64 module I think either this shouldn't try to do this and should error explicitly that it's not supported, or it should work if it's within scope/spec. I'd argue an internal error saying the URL is invalid (when both package.json and the data URL are valid) is confusing here for most nodejs developers. ### What do you s…
