Chore/improve base react template #trivial

[kaisermann]

What problem is this solving?

• Adds typings for css and graphql/gql files.
• Removes unnecessary options from tsconfig.json
• Add default base component (Index.tsx)
• Move default base test next to the tested file
• Simplified the .vtexignore and added the *.test.* pattern
