Support for PowerShell

[mi-hol]

System integrations are frequently implemented as shell scripts and PowerShell is getting more users every year (in 2020 progressed to rank nr 7 of most used languages on github).
One of the benefits relevant here is its build-in AST support, explained in Tobias Weltner's expert blog here

System integration requires a different domain knowledge than software development and currently lacks specific tools support, hence making Sourcetrail available would be a great improvement.

I'm a system integrator, hence can't really judge if the requirements defined in Sourcetrail language extension guide
are already met by PowerShell build-in AST support

Could you please step in here, so we can get an idea of required effort to get it going?
