fix source/doc/examples with qstkdrepo changes. (#857)

* fix source/doc/examples with qstkdrepo changes.

This handles all_os/qt/qt6_xyz_src_doc_examples changing
to all_os/qt/qt6/xyz/[unix|windows]_line_endings_src
for both list and install commands.

* configure pylint max-line-length to match others.

* Revert "configure pylint max-line-length to match others."

This reverts commit 8ebba90.
