Version 0.41.0 is not fully self-contained

[xavierpinho]

Steps:

• Tried 0.41.0 downstream (in Joern) and it complained about a missing DotNetAstGen.dll
• In https://github.com/joernio/DotNetAstGen/releases, noticed that the emitted assets are considerably smaller when compared to the previous release, e.g. from ~50MB to ~10MB
• Locally, running ./build-with-version 0.41.0 and ./publish-release osx x64 outputs the expected standalone file. Not sure what changed in CI.

Opening this issue in order to alert that 0.41.0 isn't usable.

We could try passing the extra relevant flags to dotnet, viz. --self-contained true etc. (in pr.yml) to check that it works once again but, ideally, would be best to understand what went wrong with this version.
