Initial implementation of friendlier errors

[patrick91]

I'll add a proper description later, this PR is just for testing the CI steps.

Related: #2107

TODO:

• [x] assert that documentation exists (via pytest)
• [x] make all of this optional (flag and checking for imports)
• [x] Don't fail bad if ast parsing fails (for example with dynamic code)
• [x] don't add libcst as main dependency
• [x] print standard exception if we can't find the source (?)
• [x] redirect from errors.strawberry.rocks

Future release:

• [ ] Errors in wasm (if libcst works)

Maybe:

• [ ] custom flake8 plugin to disable pytest.raises with StrawberryExceptions

Thanks for adding the RELEASE.md file!

Here's a preview of the changelog:

---

This release introduced improved errors! Now, when you have a syntax error in your code, you'll get a nice error message with a line number and a pointer to the exact location of the error. ✨

This is a huge improvement over the previous behavior, which was providing a stack trace with no clear indication of where the error was. 🙈

You can enable rich errors by installing Strawberry with the cli extra:

pip install strawberry-graphql[cli]

Here's the preview release card for twitter:

Here's the tweet text:

🆕 Release (next) is out! Thanks to @patrick91 for the PR 👏

from discord:

we should make this error better, if not already done here:

import strawberry
from strawberry.scalars import JSON
strawberry.union(
    name='NamedUnion',
    types=(
        # some other types
        JSON,
    ),
)

AttributeError: 'ScalarWrapper' object has no attribute 'name'. Did you mean: 'ne'.
