Fix: OpenVSX urls with versionRaw

What does this MR do and why?

Fix: OpenVSX urls with versionRaw

• This fixes an issue with OpenVSX to support installing extensions like hashicorp.terraform.
• See this issue.

History:

• Out of the box, VSCode provides a {version} parameter for resource_url_template. This {version} can sometimes include a targetPlatform (e.g. web) which actually causes Open VSX to 404.
• In this MR, we patched our VSCode fork to incldue a {versionRaw} that doesn't include this targetPlatform, which Open VSX is happy with.
• This MR updates the main project's settings to use {versionRaw} in the resource_url_template.
