Setting context inside the build element doesn't work

I am using Docker Desktop for Windows v 2.2.0.5 on Windows 10. In my case, VSCode was not able to set the container build context correctly by reading the build.context property. I fixed the issue by setting the context property as mentioned in the schema here: https://code.visualstudio.com/docs/remote/containers#_devcontainerjson-reference.

.devcontainer/devcontainer.json
