Add prerequisites for practice exercises

[TomPradat]

This adresses the issue #982

What's left :

• simple-cipher
• wordy
• secret-handshake

Maybe better: array-transformations?

[TomPradat]

Could you explain what you mean by "array-transformations" and "array-analysis", I don't get the subtlety

[SleeplessByte]

They are concepts, with existing exercises :D.

• analysis: https://github.com/exercism/javascript/blob/main/exercises/concept/elyses-analytic-enchantments/.docs/introduction.md
• transformations: https://github.com/exercism/javascript/blob/main/exercises/concept/elyses-transformative-enchantments/.docs/introduction.md

Got it 👌

[TomPradat]

I feel like this would be better to put "array-analysis" just like in "Resistor Color". IMO this could also be a good exercise to add "array-destructuring", what do you think ?

[SleeplessByte]

Sounds good @TomPradat
