chore(genesis): Rename HardForkConfiguration

[refcell]

Description

Been wanting to do this for a while.

We've been inconsistently naming configuration types across our codebase.
Some have the suffix "Configuration" while others have "Config".

This PR renames HardForkConfiguration type to HardForkConfig and
deprecated a new HardForkConfiguration alias to improve devx.

I don't see a need to spell out the full "configuration" blurb when most
everywhere just uses "config" to denote a configuration, but open to discussion.
