Minimal repro here: https://github.com/chenxinyanc/unrs-resolver-mounted-partition

When resolving for a module, if there is a mount point instead of ordinary folder within the path of the resolved file, unrs-resolver gives incorrect outputs.

I'm reporting this issue because both eslint-import-resolver-typescript and eslint-plugin-import-x are using unrs-resolver.

For example, suppose there is a Mounted Volume named "mount-root" under current directory, the following code

import path from 'node:path';
import { fileURLToPath } from 'node:url';
import { ResolverFactory } from "unrs-resolver";

const resolver = new ResolverFactory({
  tsconfig: {
    configFile: 'tsconfig.json',
  },
});
const dir = path.resolve(fileURLToPath(import.meta.url), '..');
// console.log("dir: ", dir);

const resolved = resolver.sync(dir, './mount-root/foo.ts');
console.log(resolved);

currently prints something like

{
  path: '...\\unrs-resolver-mounted-partition\\src\\Volume{3b0ca266-7f02-4f2c-938c-50931634f3fb}\\foo.ts',
  moduleType: 'module',
  packageJsonPath: '...\\unrs-resolver-mounted-partition\\package.json'
}

where "Volume{3b0ca266-7f02-4f2c-938c-50931634f3fb}" is supposed to be "mount-root".
