i18n(ja): fix mdsvgicon tag scrambled as wrapper across 4 files

[yahonda]

First-time contributors' checklist

What is changed, added or deleted? (Required)

Same MT-scramble defect as #23653, found via a corpus-wide sweep for the remaining occurrences: the self-closing <MDSvgIcon name="..." /> component was scrambled into a wrapper tag (<mdsvgicon name="...">...unrelated trailing prose...</mdsvgicon>), instead of matching its self-closing usage in the English source and elsewhere in the corpus.

Fixes 7 occurrences:

• tidb-cloud/data-service-manage-data-app.md (1)
• tidb-cloud/oauth2.md (1)
• tidb-cloud/tidb-cloud-password-authentication.md (3, identical pattern)
• tidb-cloud/use-chat2query-api.md (1)

Verified each fix against the English source (upstream/release-8.5) and the <MDSvgIcon /> self-closing convention used in sibling files. markdownlint-cli2 clean on all touched files.

Which TiDB version(s) do your changes apply to? (Required)

• i18n-ja-release-8.5 (TiDB Japanese documentation for TiDB 8.5 versions)
