Infrastructure-only change, tell mode, applying servicing-approved.

The Wasm.Build.Tests.ConfigSrcTests.ConfigSrcAbsolutePath faikure is probably related. I'll investigate it
EDIT: It doesn't repro on windows with the same node version. On CI it's just linux
EDIT2: Works also on WSL with the same node version
EDIT3: The test was failing in previous runs. Not related to this change. I'm going to remove the test from running on NodeJS

/ba-g Windows WBT passed on previous run
