Adjusted documentation about packages to v1/v2 instead of old/new

[craigcomstock]

We felt in discussion internally that v1/v2 was easier to understand especially if we also include how they are implemented:

v1 packages promise (package_method) v2 packages promise (package_module)

This leaves easier room for a v3 if that ever needs to happen.

v1(old) packages promise still has several advantages:

• support for more different package managers such as pip, brew, etc.
• support for bulk operations by default

this is related to https://github.com/cfengine/core/pull/5434 (CFE-4315) but isn't dependent on it from a code point of view so am not putting "together" so I can get a fast docs build.
