unable to override `cxExcludeFolders`

**Describe the bug**
We have a monorepo with a `packages` folder that  contains all of our packages. the `cxExcludeFolders` setting concatenates the defaults so we are unable to override it and our packages are not scanned.

**Expected behavior**
we should be able to override `cxExcludeFolders` and scan all our files

**Checkmarx CLI Command Being Executed**
Scan
