Refactor scrabble module

[RichDom2185]

Description

Generates scrabble letters using .map on words to:

• Improve editor responsiveness (smaller tokenization, less number of lines, etc.)
• Allow for single source of truth

Also generates the tiny dataset using .filter every 100 words.

The correctness is guaranteed by the introduction of additional tests, ensuring they stay the (snapshot-checking).

Type of change

Please delete options that are not relevant.

• Bug fix (non-breaking change which fixes an issue)

[RichDom2185]

I've generated the snapshots once before the refactor (refer to commit history) and can confirm that the refactor does not change the snapshots.

@martin-henz can I check what exactly qualifies for scrabble_words_tiny? Or is it handpicked? Perhaps we can generate it in a similar way, using array functions on scrabble_words.

I remember playing with the scrabble module in preparation for the PA last semester. There was a concern that the full dataset would be too large for some student's computers, so I came up with scrabble_words_tiny. I think I sampled the full set at intervals of 100:

display(array_length(scrabble_words));          // 172820
display(array_length(scrabble_words_tiny));     // 1729

[We ended up not using the scrabble module for the PA.]

Ok, I've used .filter((_, i) => i % 100 === 0) to generate scrabble_words_tiny and it seems to be an exact match with the snapshot.

This PR is ready now, thank you!

Nice!
