Explain in detail the session transactions

[devendran-m]

User Story Description:

As a developer familiar with other blockchain platforms,
I want the Casper documentation to clearly explain in detail the session transactions and highlight the key differences in how concepts like session transactions, contract transactions, and token operations are implemented,
so that I can quickly understand the unique aspects of the Casper Network and adapt my development approach accordingly.

Acceptance Criteria:

• A dedicated section in the documentation provides a comparison of key concepts (e.g., session transactions, contract transactions, token operations) between the Casper Network and other popular blockchain platforms.
• The comparison includes a tabular format or bullet points for clarity and ease of understanding.
• Practical examples illustrate how these concepts differ in real-world implementations on the Casper Network versus other platforms.
• Explanations explicitly address the rationale behind these differences and their benefits within the Casper ecosystem.
• A guide is included on how developers transitioning from other platforms can adapt to these differences, with actionable steps and tips.
• Feedback is sought from developers experienced in other blockchain platforms to ensure the documentation addresses common pain points.
