args: [
{
displayName: 'Filename 1',

### Is there an existing issue for this?

- [X] I have searched the [issue tracker](https://www.github.com/Kong/insomnia/issues) for this problem.

### Additional Information

When I'm writing new plugin with a custom tag, I ran into a problem that a argument of type 'file' passed as a parameter of `disablePreview(args)` (also affects `liveDisplayName`) contains escaped Windows path (all file separators are trimmed).
Example:
Real path: `C:\Users\Roman.Komarevtsev\test.json`
Passed value (`args[0].value`): `C:UsersRoman.Komarevtsevtest.json`
Meanwhile, `async run(context, ...args)` receive a correct path, which can be consumed by `fs.readFileSync(...)`.

I'd like to get a real path in a `disablePreview` or `liveDisplayName` because for my tag logic I need to construct well-formed instance of `URL`.

Start at the custom-tag argument handling used by disablePreview(args) and liveDisplayName, then compare it with the path passed to async run(context, ...args). Verify the Windows file path remains intact in args[0].value while preserving the existing run behavior; the result should support constructing a URL from the preview callback argument.
