HELP tables in 11.4 and later still contain the January 2024 Knowledge Base content

MDEV-39584 replaced scripts/fill_help_tables.sql with the file generated from mariadb-docs on 10.11 (8923afa5c2c, shipped in 10.11.19). The update did not carry over in the merge-up: 11.4, 11.8, 12.3 and main still contain the content generated from the Knowledge Base on 23 January 2024. MDEV-40377 only rewrote its URLs. As a result, 11.4.13, 11.8.9 and 13.0.2 ship the 2024 help even though MDEV-39584 lists them as fix versions. For example, HELP 'reserved words' does not list VECTOR, which is reserved since 11.7 (reported in https://github.com/mariadb-corporation/mariadb-docs/issues/1250 and https://github.com/MariaDB/server/pull/5851).

The 10.11 file is also outdated. It was generated before a fix to the extractor (DOCS-6894) and contains 48 SELECT FROM (the * was stripped) and leftover code-fence markers.

Fix: take fill_help_tables.sql from the latest successful generate-help-tables run on mariadb-docs main (https://github.com/mariadb-corporation/mariadb-docs/actions/workflows/generate-help-tables.yml) and apply it to 10.11 and 11.4 and up. Verified with the run from 2026-10-16 (b0baa86) on 13.0.2: it loads through mariadbd --bootstrap without errors, and HELP 'reserved words' lists VECTOR (11.7+).
