I'm sorry, I can get it to work. I don't have any experience with dev containers. Could you update the description to give a more detailed "guide" on how to review, or link to some resources on that?

I just checked this PR branch out and "Reopen in in container" locally.

After allowing the "unsafe" git repo (prompt from VS Code) I could do the following things:

• ✅update code and commit it
• ✅install the dependencies (happens automatically)
• ✅build the project
• ✅build the docs
• ✅serve the docs
• ✅run linter
• ✅run tests

I will approve so it's not blocking, but feel free to rethink about vscode recommendation
it could get annoying to recommend extensions that are not really needed at the end of the day

And updates for this PR?
It has two approvals for several days now
As I won't use this anyways it is not such important for me what is configured in it, so go on and merge as you like
