fix(lib): doom/reload-theme not reloading active theme
fix(lib): doom/reload-theme not reloading active theme

Rather than reloading whatever `doom-theme` is set to, reload the
currently active theme(s). Although `load-theme` is advised to change
the value of `doom-theme`, not all theme switching commands use
`load-theme` (e.g. `consult-theme`).
