Fix Data Catalog Integrations deployment failure: invalid heading anchor syntax

[Copilot]

Summary

Fixes the Vercel build failure from PR #5592. The heading ## Data Catalog Integrations {#data-catalog-integrations} (beta) placed text after the Docusaurus heading anchor, which is invalid MDX — {#anchor} must be the terminal element on a heading line.

Changes:

• Reordered heading to ## Data Catalog Integrations (beta) {#data-catalog-integrations}
• Applied the Data Catalog Integrations section (content, table, image component) from PR Add Data Catalog Integration to Integrations Page #5592
• Added static/images/cloud/features/data-catalogs-ui.png (referenced by import but absent from the branch)

Checklist

• Delete items not relevant to your PR
• URL changes should add a redirect to the old URL via https://github.com/ClickHouse/clickhouse-docs/blob/main/docusaurus.config.js
• If adding a new integration page, also add an entry to the integrations list here: https://github.com/ClickHouse/clickhouse-docs/blob/main/docs/integrations/index.mdx

@copilot where do the links to the data lake guides like unity catalog get declared in the sidebar

The data lake guide links (Unity Catalog, Glue, etc.) are declared in two places in sidebars.js:

1. Data lake use-cases section (main navigation) — uses autogenerated to automatically pick up all .md files from the docs/use-cases/data_lake/ directory. That directory contains individual guide files: unity_catalog.md, glue_catalog.md, rest_catalog.md, onelake_catalog.md, nessie_catalog.md, and lakekeeper_catalog.md.

2. SQL Reference section — has a "Data Lakes" category that links to sql-reference/datalakes.

So to add a new data lake guide to the sidebar, you just drop a new .md file into docs/use-cases/data_lake/ and it will automatically appear in the sidebar.
