NOTES:
TestingPlatformShowTestsFailureandTestingPlatformDotnetTestSupportare specific to running Microsoft.Testing.Platform test apps with the old VSTest-baseddotnet test. This will no longer be relevant for Microsoft.Testing.Platform 2.x which is used by MSTest 4.x.- Running MTP test apps with
dotnet testwill requiredotnet.configsetting test runner to MTP. So far, the template doesn't create that.

Description
We would like to update templates for MSTest to version 4 that is currently under development and that we will ship just before net10 is finalized. We want to make this change now, to have our changes dogfooded, and keep pushing newer versions mstest v4 previews into the templates until the release of .NET.
Customer Impact
Users creating new test projects for mstest will use v4, while previously they would use v3. Users are able to change the versions back to their preferred version by editing the generated files. Or they can migrate their other projects to v4 using this migration guide: https://learn.microsoft.com/dotnet/core/testing/unit-testing-mstest-migration-v3-v4 Breaking changes to v4 were kept to minimum.
NOTE: MSTest support policy explicitly states:
Regression?
No.
Risk
Low.
Users are able to easily revert their dependency versions to target MSTest v3. Once MSTest v4 is finalized, it will become the official release of MSTest and the only supported version of MSTest. Which is why we want to make the change now.
Link the PR to the original issue and to the PR to main.
Note any packaging impact. (If the changes touch code in a package that we ship out of band (OOB) then we will need to take care to ensure those packages ship.)
No impact.
Note any ref pack impact.
No impact.
