[dinesh-2047]

Description

This Pull Request introduces a new sql-datatypes.md file to the website's documentation, addressing the critical gap in SQL data types content as identified in Issue #331

Fixes #331

Type of Change

• New feature (e.g., new page, component, or functionality)
• Bug fix (non-breaking change that fixes an issue)
• UI/UX improvement (design, layout, or styling updates)
• Performance optimization (e.g., code splitting, caching)
• Documentation update (README, contribution guidelines, etc.)
• Other (please specify):

Changes Made

The changes include adding a comprehensive file with beginner-friendly explanations of Numeric (TINYINT, INT, FLOAT, DOUBLE, BIGINT), String (CHAR, VARCHAR, BLOB), Date/Time (DATE, YEAR), and Other (BOOLEAN, BIT) data types, complete with practical examples using CREATE TABLE and INSERT INTO statements, formatted output tables in sections, and the integration of assets/datatypes.png as a visual aid. Additionally, "Pro Tip" and "What NOT to Do" sections (e.g., avoiding FLOAT for money and recommending DECIMAL instead) have been included to guide learners, all presented in a friendly tone with structured metadata (e.g., id: sql-datatypes, sidebar_position: 5, tags like sql, data-types) to align with the existing style (e.g., filtering-data.md).
