fix: multiple .net versions issue fixed

Context

• Fixes Exit code "1" after sucessfull rerun #165
• Added a description regarding the language dependency of the tool.
• Improved exception output.
• Added and updated some tests.

Description

The original issue was related to handling many projects with different .NET versions. The dotnet command searches for test DLLs in subfolders defined in a test project. However, if the test is run for a solution with the --no-build flag, the search subfolder might be incorrect. This leads to an error even for a DLLs with all tests passed (net8 subfolder is wrong):

The test source file "c:\Projects\Local\dotnet-test-rerun\test\dotnet-test-rerun.IntegrationTests\Fixtures\XUnitTwoMultipleProjectsWithDifferentNetVersion\XUnitNet48\bin\Debug\net8\XUnitSimpleTestExample.dll" was not found.

This results in an exit code 1, even if after a rerun all tests were run successfully.

The fix involves removing the addition of the framework version to the filter in the case of a test rerun. However, this fix has a slight disadvantage. If the same test supports multiple .NET versions, with the fix, all versions of the test will run. The differences are visible in the DotnetTestRerun_FailingXUnit_WithMultipleFrameworks_Fails test. This is a drawback, but I still find the result better. Running all configurations of a failing test instead of just one may not be necessary, but not fixing the issue makes the tool unusable in the above-defined case.

This test works locally, I will try to fix this and recreate the PR afterwards.
