[rodrigo-pino]

Made separate files for installation and contributions, added discord and Twitter badges

Merged CONTRIBUTING.md and Contributing.md

Let's also resolve #1007 in that PR

I'd prefer the restructuring of the readme and the resources in the following manner:

1. Move contributing.md to this location and update the hyper link at here. Remove contributing.md file from the WARP codebase

2. Sync dependencies with dependencies.md and delete dependencies.md file from warp codebase.

3. A quickstart section can be added at this place moving all contents from the readme-quickstart section to there, same thing can be done for Installation section at this location. And, also for Usage section. Warp README may contrain hrefs for these resources

4. Sync Cli commands with warp cli and get rid of CLI Commands section.

5. We can create docker category at location https://nethermindeth.github.io/warp/docs/category/docker keeping all docker stuffs related to warp.

In essence, what I want (well.. it's my preference) to keep WARP README as small as possible only containing hyperlinks to the various info and resources and should include only vital infos like unsupported features, logo, warp title, social media badges and handles etc...

Pls react thumbs up if you agree with me or concern your issue with a reply.

@rjnrohit I agree with most points, but I suggest posting it in the issue #1014 or #1029. Let's do urgent changes here and talk about long term goals in the issue
