Update README with project information

[hasheddan]

There should be information about the purpose of the project, how to use it, and any governance / licensing info.

Hey @hasheddan! (fancy seeing you here)

@StrongMonkey and I would love to customize what shows up for rancher/fleet. For instance, we would love to add a link to our homepage. Is there a recommended way to do this?

I'd be happy to help with the README from what we do. Thanks!

Hey @nickgerace! Thanks for stopping by :) I am glad to hear that the site provides some use for y'all! Arbitrary information is not currently supported on the repo page, but that would be awesome to add. You can stick info in the CRD field descriptions to have them surface on the individual CRD pages, but I don't think that is quite what y'all are looking for. I imagine the best solution here would be something like what is described in #134

That makes sense to me! We do something similar for Rust Cloud Native: though it's a static, pre-commit process using JSON to edit a markdown file: https://github.com/rust-cloud-native/rust-cloud-native.github.io/blob/f77c152c9d8f2e08005e6475a02cd4fc99a0cf75/src/main.rs

EDIT: ^ it's a bit hacky, I should add, but I believe it's a similar idea
