The `mindre' theme is obsolete since Emacs 0.1

[jcowgar]

I am running emacs 30.0.50. My initialization of Mindre Theme is:

(elpaca mindre-theme
  :host 'github
  :repo "erikbackman/mindre-theme"
  (setq mindre-use-more-bold t
        mindre-use-faded-lisp-parens t)
  (load-theme 'mindre t))

When starting Emacs, I get the Warning: The `mindre' theme is obsolete since Emacs 0.1.

I see this line in code (make-obsolete 'mindre 'load-theme "0.1"), but not being a good Elisp programmer, I am unsure what I am doing right/wrong. The .el file installed does have a 0.1.5 Version header.
