[Bug] PDF page number does not update for pdf-tools continuous-scroll-mode

### Thank you for the bug report - [x] I am using the latest version of `doom-modeline` related packages. - [x] I checked [FAQ](https://github.com/seagle0128/doom-modeline#faq). - [x] You may also try reproduce the issue using clean environment and minimal configurations with the command `emacs -Q`. ### Bug description First of all, thanks for your excellent work on the awesome doom-modeline! The pdf-tools package recently introduced [continuous-scroll-mode](https://github.com/vedang/pdf-tools?tab=readme-ov-file#continuous-scroll-mode-experimental), which is an experimental feature. When `pdf-view-roll-minor-mode` is activated, the PDF page number shown in modeline will not get updated as one runs `pdf-roll-scroll-screen-backward` or `pdf-roll-scroll-screen-forward`. A quick workaround that works for me is ```elisp (add-hook 'pdf-view-after-change-page-hook #'doom-modeline-update-pdf-pages) ``` Currently, the doom-modeline replies on `pdf-view-change-page-hook` instead of `pdf-view-after-change-page-hook`: https://github.com/seagle0128/doom-modeline/blob/master/doom-modeline-segments.el#L2578 So perhaps a quick solution to this issue is to use the `pdf-view-after-change-page-hook`. ### Steps to reproduce - Open a PDF in Emacs using pdf-tools - Activate the continuous-scroll-mode by `M-x pdf-view-roll-minor-mode` - Scroll down the pages by `M-x pdf-roll-scroll-screen-forward` ### Expected behavior The page number shown in the modeline will be updated when one scrolls down/up to a new page. ### OS MacOS ### Emacs Version 30 ### Emacs Configurations _No response_ ### Error callstack ```emacs-lisp ``` ### Anything else _No response_
