feat: update version of docsy to 03eede2

[h1z3y3]

I'm getting into the Chinese translation, but found some bugs of docsy, so I update it to latest version.

There were some updates of docsy, like this added some i18n message for zh.toml, it's necessary for Chinese:
https://github.com/google/docsy/pull/826/files

What updated:

1. update the docsy to the latest version: 19e0072b
2. import docsy as hugo module, for more information: Docsy as a Go module? google/docsy#535, and this release of docsy is the last release with submodule-only support: https://github.com/google/docsy/releases
3. fix duplicate zh*.toml i18n file, this is my PR in docsy: fix: there is no need existing two i18n/zh*.toml files google/docsy#832

@myitcv
After a few days this PR was still open,
I've updated theme to the theme/docsy latest version.
Bring some good features and fix some i18n bugs, please help me to review 😊

Wonderful, thank you for taking the initiative here!

Got some questions about the change.

Following this PR I also can't develop things locally using the version configured in:

cuelang.org/netlify.toml

Line 10 in 2666f04

HUGO_VERSION = "0.89.4"

It hangs on:

$ huge serve -D
hugo: downloading modules …

Does that now need to change?

[myitcv]

@h1z3y3 - thanks for your patience on this PR. Now merged.

[h1z3y3]

I'm the one to say thank you.
Thank you for taking CUE to the world.

I will do further work when docsy go module version is stable.

[myitcv]

Thanks very much! Wonderful that you are taking the initiative here.

If you are starting work on translations, perhaps you could comment on via cue-lang/cue#970?

That way others can help review, contribute etc?

[h1z3y3]

Okay. I'm working on translation of https://curatorials.com and I have finished some pages. It's also an awesome website introducing CUE.

I'll start on cuelang.org later.

But what obstructs me is that docsy i18n still has some bugs on Chinese version.

It will be soon, don't worry. Thanks
