Merge pull request #328: Adding winget workflow

Adding a shiny new workflow to publish releases to winget! 🥳

I validated this workflow locally by successfully opening a [PR](https://github.com/ldennington/winget-playground/pull/4) against my winget-playground repo and running `winget validate` to ensure the generated manifest adheres to winget's required schema. Any feedback on the fields I've included (\*cough\* `ShortDescription:` \*cough\*) or suggestions for additional fields/values are welcome!
