Add a remote installation script

[nomicode]

I would like to be able to install my dotfiles where:

• The default GitHub dotfiles installation fails
• The local dotfiles configuration is lost or corrupted (etc.) inside a running container, or
• There is no default installation process (e.g., outside of GitHub Codespaces)

To accomplish this, a method that pipes wget or curl to sh could work (e.g., like the Homebrew installation process).
