Wrong dependency information on GitPage

[Indribell]

Add this project as a dependency in your Package.swift file.
.Package(url: "https://github.com/PerfectlySoft/Perfect-PostgreSQL.git", majorVersion: 3)

• Package is incorrect as Swift now uses lowerscore Package.
• majorVersion is incorrect as its now "from"
• 3 is incorrect as its now "3.0.0"

So the correct syntax needs to be:

.package(url: "https://github.com/PerfectlySoft/Perfect-PostgreSQL.git", from: "3.0.0"),
