Webviews do not work in built server

[alexdima]

• run e.g. yarn run gulp vscode-reh-web-darwin
• launch ./vscode-reh-web-darwin/server.sh
• open in web and try to preview a markdown file
• observe error:

NOTE: I think the problem is related to an assumption that the bits are available at a certain URL

The root cause of this seems to be that product.commit is set to the current git commit. This means that we try pulling the webview bits from a CDN commit that doesn't exist

The standard oss builds don't set product.commit so not sure if the OSS server needs to

Looks like commit is set in these files:

https://github.com/microsoft/vscode/blob/42a0825e8ee30dc942adac00467200a8aa2f93a1/build/gulpfile.reh.js

vscode/build/gulpfile.vscode.web.js

Line 29 in 42a0825

const commit = util.getVersion(REPO_ROOT);

Hardcoding commit fixes the issue but I think this will break our normal builds

Needed to revert 1100001 to unblock the build, so reopening this issue.
