Setting up GPG key for signing commits

See https://docs.github.com/en/github/authenticating-to-github/managing-commit-signature-verification/signing-commits and https://docs.github.com/en/github/authenticating-to-github/managing-commit-signature-verification/telling-git-about-your-signing-key

TEST

Potentially quicker version (of above) that worked on my Mac (it did not cache my gpg key password, so maybe it doesn't work - follow above instructions)

git config --global commit.gpgsign true
curl https://releases.gpgtools.org/GPG_Suite-2021.1_105.dmg -o GPG_Suite.dmg
open GPG_Suite.dmg
gpg --list-secret-keys --keyid-format=long

From last command stdout:

/Users/hubot/.gnupg/secring.gpg
------------------------------------
sec 4096R/3AA5C34371567BD2 2016-03-10 [expires: 2017-03-10]

Get the key id (e.g 3AA5C34371567BD2) :

git config user.signingkey 3AA5C34371567BD2
