Release version.md

Steps to take when releasing new version

This is just a checklist for myself.

1. Update ChangeLog.md
2. Bump version in package.yaml
3. Run stack build
4. Run stack sdist and upload to hackage
5. Run snapcraft and snapcraft upload --release=stable hascard_a.b.c.d_amd64.snap
6. Commit with version tag and push to github

git add .....
git commit -m .....
git tag va.b.c.d
git push --tags origin
git push origin master

7. Wait till Travis CI completes, and then download the macos release
8. Run shasum -a 256 hascard-va.b.c.d-osx.tar.gz
9. Update Yvee1/homebrew-tools/hascard.rb url and sha256
