Getting GPG info from `gh` & GitHub

@namcios,

You might find these code snippets useful:

```
#!/bin/bash

if [[ $(command -v gh) == "" ]]; then

printf "No \`gh\` Installed!\n"
brew install gh
printf "Installed \`gh\`.\n"
fi

if !(gh auth status --hostname "github.com" > /dev/null 2>&1); then
printf "You are not logged into \`gh\`!\n"
printf "Authenticate gh with GitHub using the Web and set ssh as default.\n"
gh auth login
printf "Logged into GitHub.\n"
fi

# Get the GitHub User Name from GitHub's `gh` cli config files
My_GitHub_User=$(cat <~/.config/gh/hosts.yml | grep -A0 user: | cut -d: -f2 | tr -d ' "')

printf "My_GitHub_User:\t$My_GitHub_User\t✅\n"

## Setup gnupg

## install gnupg if it is not already instealled
if [[ $(command -v gpg) == "" ]]; then
printf "No GPG Installed!\n"
brew install gpg2 pinentry-mac
printf "Installing gpg & pinentry-mac\n"
fi

My_GPG_Key=$(curl https://github.com/$My_GitHub_User.gpg 2>/dev/null)
if [ -z "$My_GPG_Key" ] ; then
script_exit "ERROR: Unable to find $My_GPG_Key from https://github.com/$My_GitHub_User.gpg!\n" 1
else
printf "My_GPG_Key:\tRETREIVED\t✅\n"
fi

export GPG_KEY=$My_GPG_Key

## Get GPG Fingerprint from $My_GPG_Key
# For instance https://github.com/ChristopherA.gpg
# $My_GPG_Key would equal "FDFE14A54ECB30FC5D2274EFF8D36C91357405ED"

My_GPG_KEY_Fingerprint=`echo $My_GPG_Key 2>/dev/null | gpg --with-colons --import-options show-only --import --fingerprint 2>/dev/null | awk -F: '$1 == "fpr" {print $10}' | head -1`

printf "My_GPG_KEY_Fingerprint:\t$My_GPG_Key_Fingerprint\t✅\n"
```

Comece pelo snippet de shell fornecido, concentrando-se em gh auth status, ~/.config/gh/hosts.yml, no endpoint .gpg do GitHub e no comando de recuperação da impressão digital GPG. A issue não nomeia nenhum arquivo do repositório nem teste; a conclusão deve fazer com que a recuperação do usuário pretendido do GitHub e da impressão digital GPG funcione dentro do fluxo de configuração do projeto.
