Update for gatsby v3 about gatsby-remark-vscode

[zero-plusplus]

I am using machine translation.

To support gatsby v3, simply change the peerDependencies in package.json to "^3.0.0".

There might be more updates required to make this plugin fully work with Gatsby v3. I am running into this issue locally with Gatsby v3.0.4 & gatsby-remark-vscode v3.2.0:

When running local dev server, after saving for the second or third time, the dev server just hangs with:

Missing onError handler for invocation 'building-schema', error was 'Error: Schema must contain
uniquely named types but contains multiple types named "GRVSCStylesheet".'. Stacktrace was 'Error:
 Schema must contain uniquely named types but contains multiple types named "GRVSCStylesheet".

This has also been reported over on gatsby repo gatsbyjs/gatsby#30199

I am able to reproduce this in a minimal test case with gatsby-starter-blog + gatsby-remark-vscode + gatsby-source-graphql https://github.com/kremalicious/gatsby-test-case-30199

Interesting find @kremalicious. I had observed earlier that multiple type declarations seemed to merge, which was really useful. I guess that’s not allowed anymore, which is a shame.

seems to have been addressed in upstream gatsby for all similar use cases, pending new Gatsby release gatsbyjs/gatsby#30318

Great! This is why I don’t fix bugs too fast 😂

In seriousness, I’m not sure when I’ll have time to get to the rest of this issue, but if someone wants to open a PR updating the peer dep and making sure everything works, I will make the time to review it.

I just upgraded to Gatsby 3.0.1, and I'd like to install this package. When I attempt to, Get the error that the peer dependency is for Gatsby v 2.12.1. Is this still an issue?

[tnorlund]

I would really like to help out with this. I have a PR, but I'm not sure how you are handling the Jest testing. The GraphQL queries are off. If I could get the testing working, I'm sure I could increment the packages required for Gatsby V3.

[tnorlund]

How do I NPM install this to my Gatsby site?

[andrewbranch]

Released as v3.2.1. Thanks @tnorlund!
