Much clearer CTA about funding DDEV and why (Rework /support-ddev)

[rfay]

We have a reasonable statement of funding options on Github at https://github.com/sponsors/ddev

It's something. It's not great.

However, on ddev.com we don't have a clear CTA anywhere. We have https://ddev.com/support-ddev/#sponsor-development and https://ddev.com/#supporters but they're absolutely not adequate

We need to explain lots of things:

• Why we want to fund DDEV
• Why it benefits our stakeholders (the users!)
• Where the funds go
• How to go about it

A clear way to support as individual and as organization are critical.

IMO we should replace /suppport-ddev to be this CTA.
