[parmentelat]

in main we have

• notebook sometimes written noteboook with 3 o's
• mainmenu has 2 entries with the same id jp-mainmenu-jupytext-new

at first I tried to file this PR against @mahendrapaipuri's current branch lang_specific_text_nb but could not find their fork so, here it goes..

Seems like due #1165 all CI tests are failing.

@mwouts Dont bother to work on this PR anymore. This is obsolete based on new commits in #1163
