Add fork-user to winget release workflow (#1214)

## Changes
From https://github.com/vedantmgoyal2009/winget-releaser:

> If you are forking
[winget-pkgs](https://github.com/microsoft/winget-pkgs) on a different
account (e.g. bot/personal account), you can use the fork-user input to
specify the username of the account where the fork is present.

This PR makes that change.
