Plugin Directory: Required PHP string

[Clorith]

Currently the required PHP string is set as Requires PHP Version:, but this confuses users.

This leads to some user confusion, as they may know their version and it doesn't match. Adding Minimum as a prefix might be an idea here.

For WordPress version requirements we have Requires at least:. Maybe we can make this string similar?

@Clorith @Otto42 What do you think of 3574.diff​?

Looks good to me.
