fix fs module hanging not allowing code to run

Run button on Windows stopped working as CodeRunner was hanging when
executing fs.promises.mkdir as described in electron/electron#20951
It started happening after electron update to v12 in 1f515e7.
This commit adds the workaround suggested in electron/electron#19554
that fixes the issue.
