I18n: Translate labels using node UI function from node_add_menu.py

In 2a1a658492, layout functions for nodes were refactored and new
methods were introduced, but this change was not applied to the
translation extraction script.

This commit adds these method names and argument order to Python
extraction: "node_operator", "node_operator_with_outputs",
"simulation_zone", "repeat_zone", "for_each_element_zone",
"closure_zone".

Tooltips specified in a special structure are manually extracted using
`n_()`.

Actual translation is done manually in the UI methods inside NodeMenu,
in order to override the context, which by default would have been
"Operator".

Reported by Ye Gui in #43295.
