doc: remove remnants of docbook times

all xml-related tooling can go away. shell.nix is no longer useful since
the makefile is gone and the build runs entirely via a derivation, and
gitignore is thus also no longer that useful. it may filter out some
swap files, but its main reason to exist (keeping generated files out of
a concurrent build of the derivation) has gone away.
