Describe the bug

When called with an absolute path on Windows, resolvePathSync fails.

Sample code:

import { dirname, resolve } from 'node:path'
import { fileURLToPath } from 'node:url'

import { resolvePathSync } from 'mlly'

resolvePathSync(
  resolve(fileURLToPath(import.meta.url), '../plugins/router'))
  { extensions: ['.ts', '.js'] }
)

Node.js ESM resolve requires that Windows absolute paths (same limit of imports) have file proto.

I think for resolvePathSync wrapper we could identify windows absolute paths and do renormalization to avoid this issue.
