Hardcode Members stat on Home Page

[RalphOwah]

The Academy team has requested that we hard-code Members Stat on the Home Page.

Members = 9580

This figure will be used until the ongoing validation of existing users has reached a good enough number for optics, at least above 9580

To clarify @RalphOwah , @koechkevin will implement the ability to set this number manually in the WordPress dashboard. It will be up to the academy team to update it over time.
