v1.22.8

Viewer renderer: resolve shorthand links to their link text

* Viewer: When viewing documents, shortcut links are resolved to their title.
  For example: a shorthand link `tpnote:docs/20230513` that targets the file
  `docs/20230513-Animals.md` is shown as a hyperlink with the link text
  "Animals" in the browser.

* Viewer: hyperlinks with embedded images are now supported.

* The `.txtnote` renderer now parses inline images and hyperlinks with inline
  images.
