Overhaul bootstrap script to add support for GitHub Codespaces

We might also add support for Gitpod very soon, but for now, there's
an envvar override for dotfiles home which is currently not yet implemented
on shell rc files yet. Also in this commit, we're in the progress of deprecating
dotfiles-secrets in favor of PasswordStore secret storage backed by GPG.
