I18n: Translate dynamic operator descriptions

The descriptions for `POSELIB_OT_asset_modify` and
`GEOMETRY_OT_execute_node_group` are dynamic. They were already
extracted, but the translation did not happen in the description
function.

This commit adds the appropriate `TIP_` translation macro.

Reported by Ye Gui in #43295.
