Improve contribution documentation (#95)

* Add contributing guide

* Add recommended vscode extensions

* Move list of contributors to the bottom

It's also available
[here](https://github.com/nikitastupin/clairvoyance/graphs/contributors),
as well as through `git shortlog -sne` and other means.

This commit is not intended to diminish contributions of these people,
but to make README.md cleaner, so people can find it more useful.

I appreciate efforts of everyone involved in the project.

* Add poetry configuration to contributing docs

* doc: add details near ref to contributing guide

* Doc: Change IDE recommendation wording

* edits
