Temporarily disable job `psscript-analyzer` in static checks (#4837)

The job started failing consistently today with:
```
##[error]devblackops/github-action-psscriptanalyzer/v2/action.yml (Line:
30, Col: 9): Unexpected value ''
##[error]devblackops/github-action-psscriptanalyzer/v2/action.yml (Line:
30, Col: 9): Unexpected value ''
##[error]System.ArgumentException: Unexpected type 'NullToken'
encountered while reading 'outputs'. The type 'MappingToken' was
expected.
```

It seems it's something in Github that changed today that is clashing
with the `devblackops/github-action-psscriptanalyzer` action.

I've raised devblackops/github-action-psscriptanalyzer#12
