Include Model::preventAccessingMissingAttributes in docs

[Tamas-hi]

Extend the section 'configuring-eloquent-strictness' to include more 'good practice' the developer can apply.

I'm not really a fan of these features.

It seemed logical to add this since preventLazyLoading and preventSilentlyDiscardingAttributes are already documented.
In my context, preventAccessingMissingAttributes falls into the same category but isn’t mentioned in the docs.

Just wanted to note this in case it’s being reconsidered for future documentation updates.

EDIT: now I see this topic has come up a few times, and probably this is why Taylor mentioned he is not fan of the feature, caused some confusion in the past:
