Tranformers documentation translation to Portuguese
Hi!

Let's bring the documentation to all the Portuguese-speaking community :)

Who would want to translate? **Please follow our [TRANSLATING guide](https://github.com/huggingface/transformers/blob/main/docs/TRANSLATING.md).** Here is a list of the files ready for translation. Let us know here if you'd like to translate any and we'll add your name to the list.

Some notes:
- Please translate using `Você` and not `Tu`.
- Please translate in a gender-neutral way.
- Add your translations to the folder [source/pt/](https://github.com/huggingface/transformers/blob/main/docs/source/pt/)
- Register your translation in [pt/_toctree.yml](https://github.com/huggingface/transformers/blob/main/docs/source/pt/_toctree.yml); please follow the order of the [English version](https://github.com/huggingface/transformers/blob/main/docs/source/en/_toctree.yml).
- Once you're finished, open a pull request and tag this issue by including `#issue-number` in the description, where `issue-number` is the number of this issue.
- 🙋 If you'd like others to help you with the translation, you can also post in our [forums](https://discuss.huggingface.co/) or tag [@espejelomar](https://twitter.com/espejelomar) on Twitter to gain some visibility.

FYI @osanseviero @stevhliu @sgugger @mishig25 
Hey, I'll translate quicktour.mdx. <|||||>USP 🇧🇷 presente!

Obrigado @vitorfrois e @rzimmerdev! Coloquei como WIP (work in progress) os docs em que estão trabalhando 🤗. @rzimmerdev muito obrigado pelo seu PR! Se você puder, por favor, coloque aqui quais outros documentos você deseja traduzir. Podemos adicionar mais se formos mais longe 🚀<|||||>Oi Omar, eu conclui a tradução dos seguintes docs:

pipeline_tutorial.mdx
training.mdx
accelerate.mdx
multilingual.mdx
installation.mdx

Ainda pretendo concluir os seguintes:
preprocessing.mdx
model_sharing.mdx

Quando eu concluir esses ultimos dois eu dou um update sobre os próximos que vou fazer.

🤗<|||||>@rzimmerdev muito obrigado! I just added your name above to the files you already translated and the ones you plan to translate 🤗<|||||>Olá Omar,

Estou traduzindo:
* fast_tokenizers.mdx
* create_a_model.mdx

A medida que for pegando mais para traduzir vou colocando nesse comentário.<|||||>Muito obrigado @Fellip15! I added your name to the first comment in this issue for `fast_tokenizers`.<|||||>Hi @omarespejel I'd like to contribute here! 😃 🇧🇷 

I'll translate the "FINE-TUNE FOR DOWNSTREAM TASKS" section.

PS: It seems that some "How-to guides" pages is in the "Downstream tasks" section on your checklist<|||||>Oi @jonatasgrosman! Amazing 🇧🇷! I added your name to the "FINE-TUNE FOR DOWNSTREAM TASKS" section and also reviewed your #17352 PR!

Thank you for your feedback on the checklist order! I applied it 🤗.<|||||>Oi Omar, vou enviar as traduções pros arquivos que me pediu :)<|||||>Muito obrigado @rzimmerdev. Eles são chave para ter pronta a documentação para seguinte release de Transformers 🤗.<|||||>This issue has been automatically marked as stale because it has not had recent activity.
