Theia Blueprint does not create `extensions` directory

[0rzech]

Bug Description:

Unable to install plugins from Open-VSX. Most likely due to the fact, that Theia Blueprint does not create .theia-blueprint/extensions directory. After adding directory manually, the plugin installs fine, though with older version - 23.0.5 instead of 23.0.8 available here (is it because of #96)?

Steps to Reproduce:

1. Run TheiaBlueprint.AppImage
2. Go to plugins tab.
3. Search for Ada, for example.
4. Click on Install button.

@0rzech the issue has been fixed upstream in the framework but hasn’t made its way to blueprint yet (https://github.com/eclipse-theia/theia/issues/11485). The workaround as you’ve highlighted is to create the extensions folder first (this is usually necessary for new installations).

A new blueprint version was released containing the fix. Please reopen if there is still an issue with the new version.
