Fix typo in implicit outer quantifier for Example 6.43 (so'o -> su'o)

[locmene]

Describe the current content
In Chapter 6, Section 6.7 (Quantified descriptions), Example 6.43 displays [so'o] as the implicit outer quantifier for lo:

[so'o] lo ci gerku cu blabi
[some-of] those-which-really-are three dogs are-white

Proposed content
Correct the bracketed implicit quantifier from [so'o] to [su'o]:

[su'o] lo ci gerku cu blabi
[at-least-one-of] those-which-really-are three dogs are-white
(or keep [some-of] with the correct cmavo [su'o])

Additional context
The default implicit outer quantifier for lo defined throughout Chapter 6 is su'o (at least one / some). The cmavo so'o means several. Using so'o in the bracketed interlinear breakdown of Example 6.43 is a typo that contradicts the established default rule.
