make powershell terminal setting editable

[hentailing]

I got a new version of powershell7,but execute path can not setting by custom.
I can create a new powershell7 tag, but the old PowerShell is too difficult to use and cannot be deleted.

The default is there to guarantee some level of functionality with a known good/ built-in terminal. If you would like to use PS7, create a profile for it.
