remove old winget manual release ci (#8177)

# Description

This PR removes the old winget manual release ci. With the updated
winget release, we're able to specify the version we want to push to
winget manually in case it fails. You just choose the `Submit Nushell
package to Windows Package Manager Community Repository` action, click
the run workflow and specify the tag.
