Docs: Fix var types of parameters in sanitize_option() and sanitize_option_{$option}.

The related docblocks were previously defining `$value` and `$original_value` as if they were of type `string`, but they can also be of other types, like `array`.

Props gerardreches, crstauf, mukesh27.
Fixes #60214.
See #59651.
