Include php module dependencies for installing Suite 8

[samus-aran]

We need a clear list of php module dependencies when installing Suite 8 as these modules differ from legacy ( 7 ) to latest ( 8 ).

I feel this would be perhaps best on installation guide perhaps with the wording "Addition to the PHP modules required for SuiteCRM 7.x you are required the following to successfully install Suite 8"

Something like that.
