[All] Fix BuildalyzerCracker so it can work on .NET 10

[MangelMaxime]

BuildAlyzer has a bug with .NET 10, there is a fix available since 1 month
but not sign of a release for now.

For this reason, we want to use a local version of BuildAlyzer with the fix included
and remove our own version later on.

See:
- Buildalyzer/Buildalyzer#318
- Buildalyzer/Buildalyzer#319

To build the custom version of Buildalyzer

1. Clone https://github.com/Buildalyzer/Buildalyzer
2. Comment all <PackageValidationBaselineVersion> lines (in the 3 projects). I was not able to make dotnet pack work with it
3. Run dotnet build -c Release && dotnet pack -p:Version=8.0.0-fable-001

Pull request overview

This PR fixes the BuildalyzerCracker to work with .NET 10 by upgrading to a custom local version of Buildalyzer (version 8.0.0-fable-001) that includes a fix from an unreleased upstream PR. The local packages are intended as a temporary workaround until an official release is available.

• Updates Buildalyzer dependency from version 7.1.0 to 8.0.0-fable-001
• Adds local NuGet package source pointing to LocalPackages/ directory
• Includes 6 binary package files (3 .nupkg and 3 .snupkg files) for Buildalyzer components
• Documents the fix in CHANGELOG.md
