chore(cd): automatically bump winget-pkgs registered version (#340)

Resolves #332

ref: https://github.com/microsoft/winget-pkgs/pull/220105, #298

I have added the [winget section in
wiki](2e18237501...5695e45a36).

This PR aims to keep latest version in the winget-pkgs.
[This action](https://github.com/vedantmgoyal9/winget-releaser) is
widely used for this purpose.

-
3a56c32a1c/.github/workflows/CICD.yml (L261)
-
bbe1721a18/.github/workflows/winget.yml (L10)

However I couldn't test this action in my environment. Could you test
after registering the secret?

Feel free to modify the code and/or secret name in this PR.
