fix: issue when module runned by deno or bun

For some reason when deno or bun runtime environments are used
`new StackUtils().capture(2)[1].getFileName()` construct returns
file path as is on the system, not as file url

as it's visible on example below the call will just fail

```bash
$ echo "import Path from 'npm:@mojojs/path'; Path.currentFile();" > path.test.ts

$ deno run --allow-read path.test.ts
error: Uncaught (in promise) TypeError: Invalid URL: '/home/agrechkin/test/path.test.ts'
    at getSerialization (ext:deno_url/00_url.js:98:11)
    at new URL (ext:deno_url/00_url.js:405:27)
    at Object.fileURLToPath (node:url:1152:40)
    at Function.fromFileURL (file:///home/agrechkin/.cache/deno/npm/registry.npmjs.org/@mojojs/path/1.6.0/lib/path.js:186:29)
    at Function.currentFile (file:///home/agrechkin/.cache/deno/npm/registry.npmjs.org/@mojojs/path/1.6.0/lib/path.js:153:21)

```

the provided change will make sure `Path.currentFile` and `Path.callerFile` are working properly.
