Did you try this?:

---
title: "Example"
author: "Tales Martins"
output:
   pdf_document:
    toc: true
    number_sections: yes
linestretch: 1.5
---

Add in the YAML linestretch: 1.5, after that change this toc: TRUE to this toc: true and number_sections: TRUE to number_sections: yes

An example here

also you can select linestretch: 2 and others
