Geo Sites - Rename FE code from Nodes => Sites

What / Why

We have been working through a renaming in Geo from Nodes => Sites: &10069

We have taken the Facade-first approach to rename only customer facing content while leaving all the technical content like file names, method names, variable names.

This rename has reached a pretty good maturity at this point and Sites is here to say. We should now start working towards a complete rename. The Frontend code should be pretty straight forward and zero-impact to change.

Proposal

• Update Node usage to Site in ee/geo_nodes and ee/specs/geo_nodes
• Update Node usage to Site in ee/geo_node_form and ee/specs/geo_node_form
• Update Node usage to Site in ee/geo_projects and ee/specs/geo_projects
• Update Node usage to Site in ee/geo_replicable and ee/specs/geo_replicable
• Update Node usage to Site in ee/geo_settings and ee/specs/geo_settings
• Update Node usage to Site in ee/pages/geo
