[BUG] Set language to Chinese

[gaoyan0204]

Describe the bug
I want opensearch_ Dashboards language is set to Chinese.
I'm in opensearch_ dashboards.yml Set i18n.locale: "zh-CN", but the language is English. opensearch_ dashboards version is 2.1.
and I reported an error when installing the x-pack plug-in.

bash-4.2$ ./opensearch-dashboards-plugin install x-pack
Found previous install attempt. Deleting...

Currently changing the language for OpenSearch Dashboards doesn't work, and there is an open issue for it: #772. There is another open issue aims to solve it #943, you could share your opinion there.

About installing the plugin. "x-pack" plugin is not supported in OpenSearch, so I don't think the URL contains "x-pack-1.3.3.zip" is valid. Please use the plugins that supports OpenSearch.
We just uploaded the plugins that are included in opensearch-project into a public maven repo: https://repo1.maven.org/maven2/org/opensearch/plugin/, and for more info please see the issue opensearch-project/opensearch-build#1916. Those plugins are all tested and supported with OpenSearch.

When can support changing to language？
Or can you tell me how to customize the language conversion plug-in？

Hi @gaoyan0204 - for changing language settings in OpenSearch Dashboards, please take a look at the i18n OpenSearch Dashboards plugin. It should be able to do what you're looking for.
