Extract utils into separate package and bundle it when building

• Addresses the build problems we are currently seeing for Markdown headers shouldn't be exported as workspace symbols in R packages posit-dev/positron#8401
• Related to Exclude section headers from workspace symbols in R packages #858

I called the new package vscode-quarto-utils so that it shows up under vscode-editor and vscode-markdownit in the directory structure, but I am open to a different naming option here. I do think utils is too short.

OK, I think this works now. You can confirm by getting the artifact from the GH action, unzipping, and installing the .vsix.

@cscheid do you have an opinion on the naming of this new little tiny thing? We needed the logic for detecting an R package in both lsp and vscode so we moved it up. I could imagine us putting other small utilities in there in the future.

It doesn't seem right for the LSP to depend on a "vscode" module. How about quarto-lsp-utils?

[juliasilge]

It's used elsewhere in the VS Code extension not in functionality that has anything to do with an LSP, so that doesn't seem right either.

Maybe just quarto-utils?

[juliasilge]

Or quarto-workspace-utils or extension-utils or shared-utils?

quarto-utils seems good!
