Is your feature request related to a problem? Please describe.

The SectionWidget never displays for content in Jekyll Sites.

This is because Forestry exports the list of sections as collections for Jekyll sites.

Describe the solution you'd like

Pseudocode

...
if (!settings["hugo_version"]) {
  settings["sections"] = settings["collections"]
}
...

Describe alternatives you've considered
