FIX readme (again)

Please don't make me keep having to cclean this up

1) Centering of the front matter is completely wrecked

2) We are not a billboard for Discord. We have a perfectly good badge - if the *link* needs fixing, fix it.

3) Stop putting HTML in Markdown

4) We need to state who and what we are once, clearly, not 3 times...

- <b>InvokeAI: A Stable Diffusion Toolkit</b>
- # Stable Diffusion Dream Script
- # **InvokeAI - A Stable Diffusion Toolkit**

5) Headings in Markdown SHOULD NOT HAVE additional formatting
