Fields names on HomePage causes confusion

[hminnovation]

On the HomePage model we have created a promo section with promo_image, promot_title and promo_text fields (c/f https://github.com/wagtail/bakerydemo/blob/main/bakerydemo/base/models.py#L176)

This is confusing since Wagtail has a promote tab attached to all pages.

Propose renaming to lead_section or featured_section_0 (the latter would potential introduce new confusion since the other featured sections have specific represenations within the homepage template)
