chore: default ketcher2 configs in UI Feature (#1843)

- The default editor id for ketcher2 config is missing. Although the ELN Admin can set it, this migration set the default value.

NB: a missing or wrong `editor` value will prevent the option to show up in the Structure Editor Modal

- Also updated the yml example file on pair with the doc (ComPlat/chemotion_saurus#321)
