fix: restrict Node.js 22.7.x to avoid encoding issues

[SpiffyEight77]

Description

• Node.js 22.7.x has encoding issues when building CSS files, causing pagination arrows (» and «) to be rendered as question marks (?).
• close restrict Node.js version to avoid encoding issues #253

Testing

• Node.js 22.7.0 (build blocked as expected)
• Node.js 20.18.0 (working)
• Node.js 18.20.0 (working)

Additional Notes

The minimum Node.js version (16.14.0) is required by Docusaurus 2.4.3. The upper version restriction (excluding 22.7.x) is added to avoid the character encoding issues during build.
