[x] Make docs-zh : The base branch for Chinese documentation

• [ ] For every page we shall make a zh-PAGE_NAME branch.
• [ ] when this branch is complete, we open a PR against docs-zh branch.
• [ ] When docs-zh is ready with all translation pages, open a PR against master.

[ ] Create a /zh/PAGE.mdx file for every mdx page in the chakra-ui-docs package.

[ ] Make a Chinese version of the SideBar component

• [ ] Check the route to see if it contains zh/ and if it does we use the Chinese sidebar.
