MSTest: DataRow-snap file path varies by OS culture

[N-Olbert]

Describe the bug
Currently, the arguments of [DataRow] tests are transformed into string values using the actual OS culture. Therefore, the file paths may vary depending on the system locale.

To Reproduce

[TestClass]
public sealed class Test1
{
    [DataTestMethod]
    [DataRow(1.5)]
    public void TestMethod1(double value)
    {
        value.MatchSnapshot();
    }
}

Expected behavior
The snapshot file path should be identical across all systems.
Currently, on a German system it becomes something like: Test1.TestMethod1_1,5.snap
whereas on an English system it is: Test1.TestMethod1_1.5.snap

Suggested Solution
Use Invariant Culture when converting values to strings to ensure consistent file paths across different locales.
This is a breaking change, though.
