Please update the translation of the READMEs
Hello, @YifangSun @ccmorataya @dora-0 @humrochagf

Thank you for translating the READMEs.
For the next release, I have updated the README in English.
Could you update the translation in each language in Develop branch?

I changed four parts:

- modified Installation instruction
https://github.com/kitao/pyxel/commit/db5793fd86b6d5d8d5d4b7494fd03b9068abef47#diff-04c6e90faac2675aa89e2176d2eec7d8

- new API for mouse wheel
https://github.com/kitao/pyxel/commit/1143b436152d2dd043fb05fe06195e921851df78#diff-04c6e90faac2675aa89e2176d2eec7d8

- new option for the init API
https://github.com/kitao/pyxel/commit/8369951c6903e75ce9dc57ef19e83ec15c932f42#diff-04c6e90faac2675aa89e2176d2eec7d8

@humrochagf 
Sorry, I should have done all the updates at once. Can you translate the other two parts as well?
