[PT] Update lesson: Ecto Querying

[Thiago Santos]

Motivation

The portuguese translation for the lesson Ecto Querying needs to be updated.
We need to update the version of the lesson from 1.0.3 to 1.2.0.

Proposed Solution

Translate the updates of the lesson.

You can run git diff to see all differences between the versions of the lesson:

git diff a9d93d22de0a310611d019a8ffcc5f9cda303db6 HEAD en/lessons/ecto/querying.md

Tips

• Check the contributing guidelines before starting.
• Feel free to open a draft PR as soon as you start working on the translation. In order to prevent we prevent having multiple people working on the translation and also allow the reviewers to give early feedback.
• In case of any doubt feel free to comment in this issue.
