[SeaORM] fix: remove redundant prism-core import that breaks code formatting on logo hover (#167) (#168)

The HomepageExample.js files in SeaORM, SeaQuery, SeaStreamer, and SeaORM-X
imported a standalone prism-core instance and set it as window.Prism at module
scope. When Docusaurus prefetched the homepage bundle (triggered by hovering
over the navbar logo), this module-level code executed and overwrote the global
Prism instance, corrupting syntax highlighting on the current page.

Since Rust grammar is already registered via docusaurus.config.js
(additionalLanguages: ['toml', 'rust', 'bash']), these manual imports were
redundant and harmful. Removing them fixes the issue.

Closes #167
