Translate fr playground sections.json

[nfabredev]

Taking the first item on the list of #100.

Comments / questions :

• original strings are Title Cased - which seems common in English, but is not common in French so I've not title cased the translated strings
• Couldn't come up with something nice for "Fixits", as it's a TS thing it might be ok to leave the original term ?
• The translation for "Template Literals" comes from MDN

sécurité sans "e" il me semble

[nfabredev]

Oui c'est vrai ! Corrigé

[gaelollivier]

Je ne trouve pas le contexte de ce terme, est-ce que cela réfère aux fonctionnalités "auto-fix" (par exemple: microsoft/TypeScript#31938)? Dans ce cas on pourrait traduire en "Correction automatique"?

[nfabredev]

Oui c'est ça ! Je trouve le contexte des termes en allant sur la page du playground, et en cherchant dans les elements HTML la chaine de caractere que je dois traduire quand le contexte n'est pas clair.

"Correction automatique" sonne mieux en effet
