Allow use in dotnet test without spaces

[pjc50]

Having the option to enable coverlet be --collect:"XPlat Code Coverage" is very fragile because it relies on correct handling of quotes and spaces. Please provide an option to enable coverlet without spaces in the name.

Thank you for the suggestion. The data collector name requires quotes
, and the Coverlet data collector specifically uses "XPlat Code Coverage". I agree that handling quotes and spaces can sometimes be cumbersome, especially when configuring settings in msbuild (props, targets) files.
