Improvement suggestions for installation script

[lisajulia]

My colleagues and I have encountered a few additional steps during the installation process of ResInsight that may be useful for others and which can possibly be incorporated into the documentation:

• Python dependencies (https://resinsight.org/getting-started/download-and-install/build-instructions-ubuntu/#python-dependencies): We needed to create a virtual environment to install the required dependencies and custom Qt. Additionally, the make command had to be run within this Python environment.
• Qt installation: We found it helpful to install Qt in a separate folder, which may be worth mentioning in the instructions.
• Build command (https://resinsight.org/getting-started/download-and-install/build-instructions-ubuntu/#build-resinsight): The requirement to replace your_qt_path with the actual Qt path wasn’t immediately obvious. Highlighting this step could prevent confusion.
• Building without GRPC: We experienced some issues related to GRPC and discovered that running CMake with the option -DRESINSIGHT_ENABLE_GRPC=false resolved the errors. This could be a useful note for others facing similar problems.
