Some of the generated documentation depends on the devicetree scripts.
E.g. the bindings index uses edtlib.
We don't have a well-defined interface boundary here for managing
dependencies, so let's just add the entire dts directory to the
'paths' glob list in doc-build.yml. This will ensure we don't
accidentally change some DT implementation detail in a way that breaks
the docs.
