editors/tp-note: update to 1.22.6

New shortcut notation to link Tp-Note documents

* Links in Tp-Note documents: Add new optional scheme `tpnote:` for local links,
  e.g. in Markdown the autolink `<tpnote:dir/my%20other%20doc.md>` targets
  `dir/my other doc.md`. The link is displayed as `my other doc`.
* Configuration: the variable `filename.extensions` groups all former
  `filename.extensions_*` variables (config breaking change).
* Viewer: internal improvements handling HTML escape codes and percent codes
  in URLs.
* Integration: register additional Tp-Note files extension: `.txtnote`. The
  viewer only links, no markup.
* Template: new filter: `link_text_picky`, similar to `link_text`. The latter
  always return the fist link found, `link_text_picky` rejects obvious
  meaningless link text content.
