* Allow `gh auth git-credential` to authenticate GitHub Gist requests
When there are stored credentials for `example.com`, allow using them to
authenticate requests to `gist.example.com` as well.
* Fix writing out of credential config
* remove unneccessary function
* actually delete

Fixes non-interactive login flow and make sure "prompt" configuration is
respected by never prompting if it was explicitly disabled.
No longer asks to press Enter again after "Authentication complete"
message, since that didn't provide any value to the user.
Adds a new command `gh auth setup-git [<hostname>]` that sets up git to
use the GitHub CLI as a credential helper.
The gist is that it runs these two git commands for each hostname the
user is authenticated with.
```
git config --global --replace-all 'credential.https://github.com.helper' ''
git config --global --add 'credential.https://github.com.helper' '!gh auth git-credential'
```
If a hostname flag is given, it'll setup GH CLI as a credential helper
for only that hostname.
If the user is not authenticated with any git hostnames, or the user is
not authenticated with the hostname given as a flag, it'll print an
error.

When there was a previously valid token that was granted some scopes,
ensure all those scopes will be re-requested when doing the
authentication flow for the new token.
This keeps git operations working even when PATH is modified, e.g. `brew
update` will work even though Homebrew runs the command explicitly
without `/usr/local/bin` in PATH.
Additionally, this inserts a blank value for `credential.*.helper` to
instruct git to ignore previously configured credential helpers, i.e.
those that might have been set up in system configuration files. We do
this because otherwise, git will store the credential obtained from gh
in every other credential helper in the chain, which we want to avoid.
Before:
git config --global credential.https://github.com.helper '!gh auth git-credential'
After:
git config --global credential.https://github.com.helper ''
git config --global --add credential.https://github.com.helper '!/path/to/gh auth git-credential'
Old message:
read-only token in GH_TOKEN cannot be modified
This message was vague and some users did not understand that this
refers to the value that is read from environment variables.
New message:
$ GH_TOKEN=123 ghd auth login -h github.com
The value of the GH_TOKEN environment variable is being used for authentication.
To have GitHub CLI store credentials instead, first clear the value from the environment.
