The web extension does not export any API

[amblafont]

Describe the bug

extensions.getExtension('ejgallego.coq-lsp').exports is undefined when coq-lsp is running on vscode.dev.

To Reproduce
Try the above line in a new vscode web extension, with coq-lsp already installed. To test the new web extension, I used the @vscode/test-web method documented here: https://code.visualstudio.com/api/extension-guides/web-extensions#test-your-web-extension.

Expected behavior
I expect this line to return an object of type CoqLspAPI (as it does when the extension is running on desktop)

Desktop (please complete the following information):

• coq-lsp version 0.2.2
• VS Code version 1.95.3

Additional context

I would like to reimplement Coreact-yade as a web extension exploiting the new features of coq-lsp (full implementation of coq running in vscode.dev)
