Github Action to auto push new releases to Winget package registry

[jo-chemla]

Note, in the meantime, I've created a cron running every night via a github action that pushes new yq github releases to winget registry as soon as they are detected. Since it would be preferable to have the official yq package published to winget via a repo workflow, the below github action does this.

Uses winget-releaser 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. Review #172 for information.
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.
