[FEATURE] Please add a variable for the main folder name of the KiCAD project

[rainer38]

Is your feature request related to a problem? Please describe.
I need a variable which contains the main KiCAD project folder name without the whole path.
For example if the project path would be "/home/user/Documents/kicad_project/testfile.kicad_pcb" the variable would contain "kicad_project".
My projects does not always have the same file- and folder name but the folder name is the one i need for generating output files.

Describe the solution you'd like
Please add a variable like %M (or something else) which represents the folder name of the KiCAD project.

Describe alternatives you've considered
I wrote a little python script which extracts the folder name and substitutes placeholders within the kibot.yaml file. But than i have to create custom configuration files for every project instead of using a global configuration.
