Push Japanese documentation translations upstream
What does this MR do?
This MR contains translations for content committed by the GitLab Argo Bot  to the main-translations branch of our production fork of GitLab Chart  up to GITTECHA-30 #1.
We are translating all content in the /doc directory into japanese, and delivering these translations back to the project in the /doc-locale/ja-jp/ directory.
This change is needed so translations are available as our technical documentation is internalized in Japanese ->  docs.gitlab.com/ja-jp/ (not live yet!)
You can stay informated on the status of translating this content in https://gitlab.com/gitlab-com/localization/docs-site-localization/-/issues/65
This MR builds on https://gitlab.com/gitlab-org/gitlab-runner/-/merge_requests/5513
