DOCS-2743 / 13.3 / MinIO/AIStor trademark legal compliance (13.3)

[DjP-iX]

Summary

Part of DOCS-2743 (MinIO Legal Compliance), branch 13.3 — the final branch in this project. Fixes a casing bug in a shared include (marking its first-and-only-mention status for 3 consuming stub pages), marks first mentions on two other pages, fixes one more casing bug, and appends the required attribution sentence everywhere MinIO is named to a reader.

• layouts/shortcodes/trademark-notice.html — new self-contained shortcode, matching the pattern already approved on 26/25.10/25.04/24.10/23.10/13.0.
• static/includes/S3Deprecation.md — casing fix + first-mention mark (Minio applications → **MinIO™** applications). Consumed by 3 stub pages whose entire body is this one include call — no cross-page conflict, genuinely first mention for all 3.
• content/GettingStarted/COREReleaseNotes.md — a repeated boilerplate paragraph appears twice; marked the first occurrence, fixed a casing-only bug in the second (leaving unrelated capitalization alone).
• content/GettingStarted/Deprecations.md — first (and only) mention marked.
• content/CORETutorials/Services/ConfiguringS3.md, content/CORETutorials/Services/S3forMinIO.md, content/UIReference/Services/S3Screen.md — attribution appended (consuming the shared include's mark).

What wasn't needed on this branch (all confirmed, not assumed):

• No taxonomy fix needed — confirmed via content-block-scoped inspection that all 3 stub pages' .Summary truncates before reaching the marked sentence on the relevant tag page (s3); the only "minio" noise inside S3forMinIO's article block traces to its own URL slug (s3forminio contains "minio" as a substring) plus its already-correctly-cased title, not real content leakage.
• content/CORETutorials/JailsPluginsVMs/_index.md — an old URL redirect alias only, same non-issue pattern as 13.0.
• static/api/{core,scale}_websocket_api.html — auto-generated API example content, same as every prior branch.
• One accepted, carried-forward non-issue: static/includes/S3Deprecation.md's raw static-passthrough copy shows the mark without adjacent attribution — the same pre-existing, site-wide Hugo structural characteristic already ruled non-actionable on 25.04/22.12/13.0.

Note: this branch's CI pins Hugo v0.145.0; the default hugo in the build environment used for verification is newer and fails on an unrelated, pre-existing duplicate-YAML-key bug in data/properties/scale-downloads.yaml — building with the pinned 0.145.0 binary confirms this diff is unaffected by that issue.

Test plan

• Clean build with Hugo v0.145.0 (this branch's CI-pinned version): exit 0, 0 ERROR lines.
• All 5 affected pages render exactly 1 attribution sentence and exactly 1 mark each.
• Content-block-scoped taxonomy check on the s3 tag page — zero leaks.
• Site-wide source sweep and mark-without-attribution sweep — only the known, accepted raw-passthrough non-issue remains.
