Commit Message

Ref SDK 10.0.300 (Runtime 10.0.8) to release Ocelot v25 beta 3 and Ocelot.Testing v25 beta 8+ (#2389)

* Prepare to release Ocelot.Testing v25.0.0-beta.8 package
* Bump all packages to the latest versions, including .NET SDK 10.0.203 (Runtime 10.0.7) released April 21, 2026
* Migrate unit testing from VSTest framework to Microsoft.Testing.Platform
* Do not use 'Cake Build' step in PR workflow, use plain dotnet scripting instead
* Fix "Unit Tests" step in PR workflow
* Rename job to "build" since it's not Cake anymore
* Suppress non-zero result and check test running status
* Update "Acceptance Tests" step
* Don't collect Coverlet code coverage data in "Acceptance Tests" step
* Update prepare-coveralls.sh
* Prepare Coveralls script v2
* Prepare Coveralls script v3
* Prepare Coveralls script v4
* Prepare Coveralls script v5 -> Add 2nd BUILD_CONFIGURATION argument
* Upgrade to SDK 10.0.300 aka Runtime 10.0.8
* Update samples
* Update workflows: prefer plain dotnet scripting over Cake Build
