x/website: tutorial -replace=old=new doesn't work in powershell

[migberbay]

Hi! I was chekcing the intial tutorials for making modules, and this site is using the wrong syntax in this line:

$ go mod edit -replace=example.com/greetings=../greetings

and it should be:

$ go mod edit -replace example.com/greetings=../greetings

I'm using the newest version of go at the time, 1.16

Seems like a powershell issue

I think this is probably a duplicate of #43179 and an example of the still unfixed PowerShell/PowerShell#6291.

I guess the question here is whether we want to change the tutorial to work around the Powershell issue, or not.

For now we should just change the command to :
go mod edit -replace example.com/greetings=../greetings

SO that more beginners don't get stuck on this error.
