Add Razor Tooling Bug report issue template (#23961)

* Add Razor Tooling Bug report issue template

- Given we're going to start providing a new Razor tooling editor experience we expect our users to hit a number of issues. To optimize their path of filing an issue we're creating a bug template for them to use. In parallel we're also working with the VS report an issue tool to gather additioanl data so we can encourage users to go the typical "report a bug" route for VS scenarios.

Fixes dotnet/aspnetcore#23551

* Addressed code review feedback.

* More feedback.
