fix(release): remove duplicate GitHub Release creation step

The 'Create GitHub Release' step was conflicting with dotslash-publish-release.
Both were trying to upload assets to the same release, causing the 'asset under
the same name already exists' error.

Removed the softprops/action-gh-release step since facebook/dotslash-publish-release
handles creating the release and uploading all assets including the dotslash manifest.
