README is missing the part, that the shell commands need to be installed before checking it with the scanner

[jan-steffen]

When i checked my installation the first time, the scanner told me, that Visual Studio Code has not been found, even if it is installed.

[~/glassworm-detect]:./glassworm-detect.sh

VSCode installations found: 0
✓ CLEAN: No infected extensions found!
  Your system appears to be safe from Glassworm.
Scan log saved to: glassworm-scan-20251024-081917.log

The scanner only checks the installation if the code shell command has been installed in advance:
see https://code.visualstudio.com/docs/setup/mac
To run VS Code from the terminal by typing code, add it to the $PATH environment variable:

This suggests the system is clean, even if it may not!

After adding it to the $PATH variable, the output of the scanner looks different:

[~/glassworm-detect]:./glassworm-detect.sh

At least this should be added to the README file as a step of the initial installation.
