fix: 📌 add replace commands to go.mod files

[mhornbacher]

This is currently an ongoing issue with go.work configurations in golang/go#50750

As discussed in nx-go/nx-go#127 we should update the demo to demonstrate an actual setup so that other engineers running across this issue can see a clear demonstration of how it needs to be fixed.

For example nx-go-playground/math needs to be replaced in both nx-go-playground/cli and nx-go-playground/geometry even though it is only depended upon in nx-go-playground/geometry as the entire chain needs to be replaced in order for go get to work properly.

Note that this is not required for go build or go run. Just for updating dependencies.
