bug#42332: Function to add projects to project--list

[Sean Whitton]

Hello,

I just added this to my init file, but it uses the private function
project--add-to-project-list-front -- it would be good to have an API
function to add arbitrary projects from Lisp.

    (defun spw/register-programming-projects-and-switch ()
      (interactive)
      (dolist (directory (spw/all-programming-projects))
        (when-let ((project (project-current nil directory)))
          (project--add-to-project-list-front project)))
      (call-interactively 'project-switch-project))
