"Promoted to front page" for new content types should default to Un-Checked

Problem/Motivation

When creating a new content type, the default value for the "Promoted to front page" checkbox should be FALSE.

Proposed resolution

Set the default value of promote to FALSE in Node's base field definition
This value propagates to the Node type on save via base field override configuration

Existing node types will need an upgrade path to create base_field_override config to maintain the previous default setting.

Remaining tasks

Write upgrade path for existing node types
