Add the winget package for thinkrail

## Problem

What problem are you trying to solve? What's the motivation?

- I hope there is a usable winget package for thinkrail, making it easy to install on Windows.

- This implies either manually opening a new PR at https://github.com/microsoft/winget-pkgs after every release, or adding a GitHub Actions configuration to the current repository so that a GitHub App automatically opens a new PR at https://github.com/microsoft/winget-pkgs once the release is complete.

## Proposed solution

What you'd like to see happen.

- Add the winget package for thinkrail.

## Alternatives considered

Any alternative approaches you've thought about.

- Null.

## Additional context

Anything else that would help — mockups, links, related issues.

- Null.

Start by reviewing the repository's release process and the linked microsoft/winget-pkgs submission workflow. Determine whether the package should be added manually or submitted automatically after releases, then verify that a completed release results in a usable Windows winget package or an automatically opened winget-pkgs PR.
