allow generation of gitignore by project type for vs and vs code

### Is your feature request related to a problem? Please describe.
I want to add gitignore file to the new .net maui project but can't find any official gitignore file that is maui specific

### Describe the solution you'd like
There is already a command `dotnet new gitignore`. Allow to create the .gitignore files for all .net project types like asp.net, maui or blazor. Also add the IDE specific files in gitignore for both Visual Studio and Visual Studio Code.
