Include libharfbuzz-dev and libfribidi-dev in rocker images

[lwaldron]

libharfbuzz-dev and libfribidi-dev are required to install pkgdown (example below on rocker/verse:4.0.2). Especially for rocker/verse, pkgdown seems popular enough to merit a couple extra, small system dependencies.

$ docker run -it rocker/verse:4.0.2 R -e 'install.packages("pkgdown")'

yeah makes sense, thanks. done

As discussed in some other places too, pkgdown dependencies ragg and textshaping are now fancier with more build-depends. And as we don't get system dependencies in automagically, this is likely the best we can do, at least for now.
