First-time contributors' checklist

What is changed, added or deleted? (Required)

Fixes a typo in releases/release-2.1-rc.1.md: INFORMMATION_SCHEMA (extra M) should be INFORMATION_SCHEMA.

Found while reviewing CodeRabbit feedback on a Japanese translation PR (#23598), where the Japanese text faithfully mirrored this pre-existing English typo. Verified the typo is present in this exact form on both master and release-8.5; this PR fixes it on master per the standard "master only, let the bot backport" guideline since it's not a feature/compatibility change.

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

• master (the latest development version)
• v9.0 (TiDB 9.0 versions)
• v8.5 (TiDB 8.5 versions)
• v8.1 (TiDB 8.1 versions)
• v7.5 (TiDB 7.5 versions)
• v7.1 (TiDB 7.1 versions)
• v6.5 (TiDB 6.5 versions)

What is the related PR or file link(s)?

• Other reference link(s): found via i18n(ja): convert full-width hash to half-width in issue/PR references (part 1/2, TiDB 1.0-4.0.16) #23598 (review comment)

AI agent involvement

• The changes in this PR were primarily made by an AI agent on behalf of the PR author.
