[Feature] Create a template to be used with dotnet new/vs/vsc

[Meir017]

the ability to create a new playwright tests project using the dotnet cli command dotnet new

with some options:

• having an argument to specify which testing library to use [nunit / mstest]
• adding a github actions configuration file
• bundle drivers? (https://playwright.dev/dotnet/docs/intro#bundle-drivers-for-different-platforms)

Very good suggestion! Once our testing harness story is done in 1-2 release we'll do it!

This seems done, there is dotnet new mstest-playwright and dotnet new nunit-playwright
