Missing dev dependency for initial built

[HerzogIgzorn]

As mentioned here, during initial serve, the UI5 build is performed. Unfortunately, I ended up with an error:

Failed to load task repository. Missing dependency to '@ui5/builder'? Error: Cannot find package '@ui5/builder' imported from C:\Users\sebastian.bender@sap.com\git\ui5-walkthrough-ts\node_modules@ui5\project\lib\graph\ProjectGraph.js

npm i -D @ui5/builder solved the issue but this is not mentioned in the tutorial step 2.

This is an issue of the ui5-middleware-serveframework and will be fixed with the cross-linked PR which closes the issue.
