[docs] I contribute Chinese docs to esbuild.

I translated the esbuild docs into Chinese: http://docs.breword.com/evanw-esbuild

And i posted the docs on some frontend community websites which are popular in China，many developers view it and know esbuild.

@evanw , If possible, i want to write a PR to add the Chinese docs link in readme.md to make esbuild spread more widely, or push the Chinese docs into esbuild repo.

Thanks.

Thank you for doing this. I'm concerned that translated documentation will become more and more out of date as time goes on, so I don't think it makes sense to add it to the esbuild repo itself. But I think it'd be fine to link to it from the readme as long as the link says what version of the documentation it represents to avoid confusion.

@evanw, Thanks for your reply.

I'm watching esbuild project and when you release an new version, i will fetch the new repo content and check if docs content updated, if so, i will translate updated content.

also, the docs highlight the current version of code:

later, i will create a PR and add the Chinese docs link into readme.md.
