[8.x] Add updateOrFail method to Model

[caugner]

The updateOrFail() method makes it more convenient to handle update errors in update actions, as it is less verbose than checking the return value of update().

[crissi]

sql drivers always throw an exception? what driver are you using?

[caugner]

@crissi I'm using the MySQL driver, but what is the difference between save() and saveOrFail() if both throw an Exception?

[crissi]

I see... did not know saveOrFail or existed.

[caugner]

The PHPDoc confirms my assumption that saveOrFail() throws, while update() doesn't:

framework/src/Illuminate/Database/Eloquent/Model.php

Lines 864 to 871 in 6de0174

	/**
	* Update the model in the database.
	*
	* @param array $attributes
	* @param array $options
	* @return bool
	*/
	public function update(array $attributes = [], array $options = [])

framework/src/Illuminate/Database/Eloquent/Model.php

Lines 986 to 994 in 6de0174

	/**
	* Save the model to the database using transaction.
	*
	* @param array $options
	* @return bool
	*
	* @throws \Throwable
	*/
	public function saveOrFail(array $options = [])

Note: saveOrFail() was added in #11202.
