Ketcher2 configuration example

[crsoph]

Apparently, the documentation on structure editors https://chemotion.net/docs/eln/install_configure/configuration#structure-editor has changed recently. To my understanding, manually downloading Ketcher2 is no longer necessary with recent versions of Chemotion.

However, the example config YAML in the documentation still contains the "extSrc" line pointing to where Ketcher2 would have been placed manually.
Is this line still important/necessary for the configuration? Does one need a ketcher section in the structure_editors.yml at all when Ketcher2 is automatically installed?
