Update ESLint's config with better rules

[antoine-cottineau]

We should have rules that are commonly used by many projects at BAM.
See this page for an inventory of the ESLint configs used in the projects.
Here are some notes taken by BaptisteM to begin creating a shared config:

Extends :[
plugin:react/recommended,
plugin:@typescript-eslint/recommended,
'plugin:jest/recommended',
'plugin:prettier/recommended',
]

Plugin :
@typescript-eslint

"import/no-named-as-default": "off", => « error »
"import/newline-after-import": ["error", { "count": 1 }],
"import/no-extraneous-dependencies": "off",
