CNA: exclude ts(js)conf.json as well as .git folder (#61412)
### What?
On windows the .git/* files are read only, when the CNA "import path" script attempts to open one of the .git/* files
### Why?
attempting to open any of the .git/* files results in an error thrown by CNA and CNA exists, hence not finishing the setup of a new project
### How?
My suggested fix uses the fast-glob ignore option to exclude the .git folder, I also moved the the ts(js)config.json exclusion into the ignore (was an "if" before)
