If you use this function to populate your `~/.ssh/authorized_keys` file
then you potentially open SSH access to anyone who is able to modify or add
to your GitHub public SSH keys, possibly including certain GitHub
employees. You should not use this function on publicly-accessible machines
and should always verify that no unwanted keys have been added, for example
by using the `-v` / `--verbose` option when running `chezmoi apply` or
`chezmoi update`.

Additionally, GitHub automatically [removes keys which haven't been used in
the last year][timeout]. This may cause your keys to be removed from
`~/.ssh/authorized_keys` suddenly, and without any warning or indication of
the removal. You should provide one or more keys in plain text alongside
this function to avoid unknowingly losing remote access to your machine.
