Build VSIX as non-prerelease
I use typically insiders (which opts people in to prereleases by default), so I never noticed that attempting to install our extension pops up an error in regular VS Code:
Given we slap the word "preview" all over this extension, I think it would be better to not mark it as a prerelease, ensuring this error does not appear for the bulk of users.
Though, maybe this is just a VS Code stable bug.
Undrafting, but we can wait a little to see if https://github.com/microsoft/vscode/issues/251730 is likely to be fixed instead.
@jakebailey As the issue is bypassed by clicking the "Install Pre-Release version" button in VS Code stable, maybe add that in the readme of the extension for now. Took me some time to stumble upon this issue :smile:
