Type model generation

Type information about .NET and PowerShell SDK methods are obtained by generating data extension files that populate the typeModel extensible predicate.

The type models are located here: https://github.com/microsoft/codeql/blob/main/powershell/ql/lib/semmle/code/powershell/frameworks/

Follow the steps below in order to generate new type models:

1. Join the MicrosoftDocs organisation to ensure that you can access https://github.com/MicrosoftDocs/powershell-docs-sdk-dotnet/tree/main/dotnet/xml (if you haven't already).

Run the following commands

```
# Clone dotnet/dotnet-api-docs
git clone https://github.com/dotnet/dotnet-api-docs --depth 1
# Clone MicrosoftDocs/powershell-docs-sdk-dotnet
git clone git@github.com:MicrosoftDocs/powershell-docs-sdk-dotnet.git --depth 1
# Generate data extensions
python3 misc/typemodelgen.py dotnet-api-docs/xml/ powershell-docs-sdk-dotnet/dotnet/xml
```

This will generate 600+ folders that need to be copied into https://github.com/microsoft/codeql/blob/main/powershell/ql/lib/semmle/code/powershell/frameworks/.

Note: Care must be taken to ensure that manually modified versions aren't overwritten.
