3proxy/.github/workflows/release-tarball.yml
Vladimir Dubrovin ad6e151b7c Publish and sign a source tarball with each release
Package maintainers, Gentoo among them, build from source and had nothing
signed to verify against: the source archive GitHub generates for a tag is
neither signed nor guaranteed to stay byte-identical.

Add release-tarball.yml. It builds 3proxy-<version>.tar.gz with git archive
from the release tag, signs the tarball and SHA256SUMS-src with the release
key, attests build provenance and uploads all four files to the release.

Also drop the SECURITY.md line about Authenticode signing, left over from the
removal of self-signed Windows binaries.

Closes #1270
