Fix typo in ruby-sapphire folder name (ruby-saphire -> ruby-sapphire)

[adammcodes]

Updates sprites submodule to fix typo in generation-iii/ruby-sapphire folder name (was misspelled as "ruby-saphire").

• See Fix typo in folder spelling for ruby-sapphire type sprites sprites#182
• This PR updates the submodule pointer to include the fix from the sprites repository.

To reproduce the issue:
Currently trying to access the type sprites in generation-iii/ruby-sapphire leads to a broken path:

https://raw.githubusercontent.com/PokeAPI/sprites/master/sprites/types/generation-iii/ruby-sapphire/17.png
--> 404: Not Found

This is because of a typo in "sapphire" in the folder name: "data/v2/sprites/sprites/types/generation-iii/ruby-saphire"
"saphire" is missing a "p".

https://raw.githubusercontent.com/PokeAPI/sprites/master/sprites/types/generation-iii/ruby-saphire/17.png
--> This works.

Correct the spelling in the version group folder name to "ruby-sapphire" so that applications that use the api version group name "ruby-sapphire" to find the type sprite for generation-iii and ruby-sapphire will not lead to 404s.
