Standardization of README.md files in IARL repositories

Analyzing the IARL repositories, we can see the absence of a standardized language in the _README.md_ files.

While the **iarl-who** and **iarl-nodejs** repositories have a description in Brazilian Portuguese, **iarl-vue**, **iarl-angular**, and **iarl-react** have a description in English.

To standardize the descriptions, which language will be used?
