Created a flag for disabling ash_paper_trail

[dallingson]

Add runtime flag to disable paper trail versioning per action

What

Adds a context flag ash_paper_trail_disabled? so you can skip creating versions for specific actions.

Why

There was no way to turn off versioning for migrations, imports, or other operations where you don't want audit history.

How to use

Option 1 – when calling the action:

Post.update!(post, attrs, context: %{ash_paper_trail_disabled?: true})

Option 2 – on the action definition:

update :my_action do
  change set_context(%{ash_paper_trail_disabled?: true})
end

Changes

• create_new_version.ex – Check the flag in valid_for_tracking? and run that check after all changes so both call-site and action-level usage work.
• Docs – New "Disabling Versioning at Runtime" section.
• Tests – Tests for create, update, destroy, bulk, and action-level usage.
• Refactor – Extracted shared logic into should_record_version_for_action?/2 and version_context/1 to remove duplication.

We should leave this logic here. We can add an additional check inside of the after_action callback.

Here are the changes... did I get this right? Let me know if there is anything else I need to change.

Lets switch to if, because unless is deprecated in newer elixir versions. Otherwise this looks great!
