Add winget-releaser github action workflow to auto publish winget package updates

[jo-chemla]

I submitted a CNRISTI.RelightLab package to the winget repository for RelightLab GUI and it just got merged, so it can now be installed on windows with a simple:

winget install CNRISTI.RelightLab

It might be useful to add a github action workflow to this repo following CreateRelease, which would automatically publish the updated winget package.

The standard way to do it is to use winget-releaser (which uses Komac). It requires a Classic Github Personal Access Token with public_repo scope is created, following this link, then the Token can be added to the repo as a secret named WINGET_ACC_TOKEN. See below, that user also will have to fork the winget-pkgs repository.

Notes:
You will need to create a classic Personal Access Token (PAT) with public_repo scope. New fine-grained PATs aren't supported by the action.
Fork microsoft/winget-pkgs under the same account/organization as the project's repository. If you are forking 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.

Here is the standard action workflow file, forgot to add it to the OP

name: Publish release to WinGet
on:
  release:
    types: [released]
jobs:
  publish:
    runs-on: windows-latest
    steps:
      - uses: vedantmgoyal9/winget-releaser@latest
        with:
          identifier: CNRISTI.RelightLab
          installers-regex: '\-windows\.exe'
          token: ${{ secrets.WINGET_ACC_TOKEN }}
