Translate the docs to other language

[sporshoroy5419]

Is your feature request related to a problem? Please describe.
KiiChain targets emerging markets (e.g., Brazil), but docs only in English.

Describe the solution you'd like
Create a stub under i18n/pt-br/README.md with basic translated intro and instructions on how to expand.

Describe alternatives you've considered
Rely on community translation, but starting structure helps.

Additional context
Low barrier—translating the homepage is a great start.

thats very nice because having a robust wide range of community is ideal for any good project. i will like to contribute in translating the docs if the vacancy is still available
