Translation of official documentation into Portuguese
#### Location of the documentation

[https://pandas.pydata.org/pandas-docs/version/1.2.1/]

#### Documentation problem

[There is no Portuguese translation. I would like to translate the official documentation and post it on my blog. And the documentation license is not specified.]

#### Suggested fix for documentation

[The Brazilian panda community is growing. And it would grow faster if it had good documentation centralized in Portuguese.]
