Overriding the default link creation function

The code below will generate a link to the generated html file instead of the default org-protocol link.

(defun org-roam-custom-link-builder (node)
  (let ((file (org-roam-node-file node)))
    (concat (file-name-base file) ".html")))

(setq org-roam-graph-link-builder 'org-roam-custom-link-builder)
