Issue Description

If your project uses the C#10 feature "constant interpolated strings" in your steps binding argument, the SpecFlow extension will no longer recognize the step as bound. The tests seem to run just fine even from the VS test explorer.

Steps to Reproduce

1. Create a SpecFlow project.
2. If reproducing before C#10 has been shipped, add this to your .csproj node preview
3. In the StepDefinition attributes, add interpolation, for example create a const string with the whole text and insert that into the interpolated string.
4. Open the feature file with the affected.

In VS2017 and VS2019 this will never work. We are using another concept in the VS2022 extension and there this could work. @epresi & @gasparnagy What do you thing about this?

Also this is a VS issue, so I move it into the right repo

@kapros @SabotageAndi Yes, this will work in the VS2022 extension, but not in the VS2019 extension. (I guess it would also work with Deveroom in VS2019 as it uses the same binding discovery mechanism as the VS2022 extension.)

As @kapros provided an repro, we should verify this with the VS2022 extension to make sure it works. I would keep the issue open until we did that.

@gasparnagy I have just switched over to Deveroom for VS2019 and it works just fine.
