Subject: [PATCH] ci: automatically create GitHub releases on push to main

When a new version is merged to main, after NuGet publish,
check whether a GitHub release already exists for the version
read from RELEASE_NOTES.md. If not, extract the release notes
for that version and create a tagged release attaching the
built NuGet packages.

This uses the GITHUB_TOKEN (permissions: contents: write is
already set for gh-pages deployment) and the pre-installed
gh CLI on windows-latest runners.

Addresses #1742
