fix: use documenso fork of skia-canvas for rendering

Use our fork of `skia-canvas` for rendering which handles
encoding characters correctly with the caveat font and other
similar fonts that can group glyphs like ligatures.

This resolves issues with pdf text extraction where characters
were unable to be extracted due to lacking any data within the cmaps.
