Center the announcement

[im-coder-lg]

I'd like to know the difference between a normal announcement(btw @sumeshir26 great that you did that!) and the one I modified. I used the <div> HTML tag and aligned it to the center(<div align=center>) so anything that you type there will be centred. The extra enters are to allow the MD tags, want to know if this is worth being on the main branch.
PS: Some realigning is needed in the README, maybe I could do it now in this PR. Also maybe I'll consider merging both the <img> tag and the banner together.

i like this because i think the announcement should be the first thing you see imo

A lil' bit more changes needed though. Will do that soon.

I'm done! What do you think?

I would put the announcement under the title, how it was before. but if you think this is better, i approve

Hmm, do people really read the Readme? I think half would need a quick abstract of the project, so that's why I kept it on the top, nvm need @sumeshir26's review on this. But my initial idea was to make users know that v0.9 is out and users can get it by visiting the link given, so what do you think about my idea?

Well i do read the readme, to see if the project interests me. But ok.

I was thinking from a novice user's perspective. They'd want a quick install, so I prioritised that.

Squash and merge? Might be better.
