Use devonfw-ide in openapi tutorials

[GuentherJulian]

Currently the windows build for the OpenApi tutorials fails. This is because windows-latest (Windows Server 2022) uses Java 8 as the default version. The Ubuntu 20.04 already uses Java 11 as default version.

Install the devonfw-ide in the tutorial so that their Java version is used.
