fix: normalize windows backslash for configFile and source

[cawa-93]

fix #47

This fix issue for me on Windows 10, but I can't test it on other platforms

Can you please check result of jiti.resolve()? It is strange if it doesn't normalize windows path as is using pathe itself (https://github.com/unjs/jiti/blob/main/src/jiti.ts)

For some reason it doesn't normalize path in all cases

{

Difference in thehe cases in extensions. 1-2 can't be resolved by resolvePathSync ( TypeError [ERR_INVALID_URL_SCHEME]: The URL must be of scheme file) and resolving by nativeRequire.resolve.
But last one resolving by resolvePathSync from mlly.

const jiti = require('.')(undefined, {
    esmResolve: true
})

console.log({
    'C:/Users/kozac/AppData/Local/Temp/c12/github_unjs_c12/test/fixture/config.ts': JSON.stringify(jiti.resolve('C:/Users/kozac/AppData/Local/Temp/c12/github_unjs_c12/test/fixture/config.ts', { paths: [cwd] })),
    'C:/Users/kozac/AppData/Local/Temp/c12/github_unjs_c12/test/fixture/config': JSON.stringify(jiti.resolve('C:/Users/kozac/AppData/Local/Temp/c12/github_unjs_c12/test/fixture/config', { paths: [cwd] })),
})

{
  'C:/Users/kozac/AppData/Local/Temp/c12/github_unjs_c12/test/fixture/config.ts': '"C:/Users/kozac/AppData/Local/Temp/c12/github_unjs_c12/test/fixture/config.ts"',
  'C:/Users/kozac/AppData/Local/Temp/c12/github_unjs_c12/test/fixture/config': '"C:\\\\Users\\\\kozac\\\\AppData\\\\Local\\\\Temp\\\\c12\\\\github_unjs_c12\\\\test\\\\fixture\\\\config.ts"'
}
