Update publish-winget action to use Komac directly (#2228)

## Changes

For the most recent release, I had to re-run the "publish-winget" action
a couple of times before it passed. The underlying issue that causes the
failure should be solved by the latest version of the action, but upon
inspection of the latest version, I found that it always installs the
latest version of [Komac](https://github.com/russellbanks/Komac). To
both fix the issue and lock this down further, I updated our action to
call Komac directly instead of relying on a separate action to do this
for us.

## Tests
