Update angular v16

[alecarn]

Un preview de la mise à jour:

• Upgrade Angular to v15 and v16
• Upgrade Angular material to MDC based
• Refact the styles with the latest IGO2-LIB styles system
• Styles adjustment

Pour tester:

• npm ci dans igo2-quebec
• Aller dans igo2-lib
• Checkout de la branche next
• npm ci
• npm run build.libs
• Copier le dossier de distribution de la lib dans igo2-quebec/node_modules/igo2
• Lancer un npm run start dans igo2-quebec
  Il est important de suivre l'ordre parce que si on relance une installation après avoir copié la librairie nous allons réinstaller la dernière version officielle de igo2-lib ce qu'on ne veut pas.

Offset of text in buttons/options is too high vertically.

When the footer is deactivated, a scroll bar appears on the map
