Some extensions throw errors during install however they seem to work

[sdirix]

Bug Description:

Installing some extensions, for example markdownlint seemingly does not complete successfully.

The dev tools show the following error

Uncaught (in promise) Error: Deployment of extension with ID vscode-extension://davidanson.vscode-markdownlint/ failed.
    at A.deploy (/tmp/.mount_TheiaIKZ4bSd/resources/app/lib/backend/527.js:2:701801)
    at process.processTicksAndRejections (VM34 task_queues:95:5)
    at async u.onRequest (/tmp/.mount_TheiaIKZ4bSd/resources/app/lib/backend/638.js:2:52196)
    at async c.handleRequest (/tmp/.mount_TheiaIKZ4bSd/resources/app/lib/backend/638.js:2:47053)

Afterwards the extension shows up both "installed" and still "installable".

Restarting Theia does not help

The extension works, i.e. I can see the markdownlint errors in Markdown files.

This is not the case for all extensions, e.g. installing ESLint worked without an issue.

Steps to Reproduce:

1. Open Theia IDE on Theia repo
2. Install recommended extensions
3. Observe error described above

I reproduced this on Ubuntu with the Theia IDE AppImage

Additional Information

• Operating System: Ubuntu 22.04
• Theia Version: 1.58.100
