Mac installation should update path so the commands as instructed

[boxabirds]

The tutorial here clearly shows "Install the libraries for your project" to be possible immediately after Step 2.

However what needs to be added is the following:

Step 3: Update your path to include the location to the vcpkg binary so you can execute the vcpkg command.

This is tedious as the user then has to find the location of the binary and update their shell, create a new one (or source to update current shell).

In this day and age I think it's reasonable that the tool also updates the path automatically so it can be run as instructed. OR add a Step 3: "add to path (dependent on your shell)".
