Contribution guidelines need updating

Is your feature request related to a problem? Please describe.

I'm trying to contribute to robotframework-lsp but don't know how to run the tests. There are a few sticking points I've noticed so far in following the directions on the Contributing page:

1. Setting up Yarn is... frustrating. I am not a Javascript developer so haven't had any experience with it. Specifically, when running yarn exec env, I get an unhelpful SyntaxError.

/usr/local/lib/node_modules/corepack/dist/lib/corepack.cjs:5422
        return this[INTERNAL].defaultPort ?? (this.protocol === "https:" ? 443 : 80);
                                           ^

SyntaxError: Unexpected token '?'

I'm on Ubuntu Linux, if that helps.

It would be helpful if there were even some mention of what Yarn is needed for. Maybe for the specific thing I want to test, Yarn isn't even required. I would be happy if that were the case.

2. No mention of Poetry, even though within robocorp-code/ I notice a poetry.lock and [tool.poetry] section in pyproject.toml. Luckily I am a heavy user of Poetry and knew what to do to install dependencies. (I deactivated my virtual environment created via the instructions on the Contrib page, ran cd robocorp-code, and ran poetry install.)
3. No instruction on setting up for tests. After running poetry run pytest from within robocorp-code/, I am getting lots of errors with AssertionError: CI_ENDPOINT env variable must be specified for tests. I could not find any instructions on what that should be set to.

Describe the solution you'd like

I want the Contrib page to be updated to address these points.

Describe alternatives you've considered

I can't think of any viable alternatives.

Humm, I don't see yarn exec env anywhere in the page... Usually I just use yarn install and it works.

Also, do you want to contribute to robocorp-code or robotframework-lsp?

You're correct. I went down the path of install page > corepack page (linked in my question) to figure out how to install yarn and found yarn exec env there. I'll give yarn install a try and get back to you.

robotframework-lsp. I thought robocorp-code was a part of lsp?

(However, since writing this question, a bug I was pursuing in LSP turned out to actually be a bug in robotframework. So I'll be looking to contribute there.)
