Description of the Change

This pull request updates the documentation for the Simple Podcasting plugin, focusing on improving organization, clarity, and accessibility of key information for users. The most notable changes include restructuring the readme.txt and README.md files, moving frequently asked questions (FAQ) into a dedicated section, and adding instructions for reporting security bugs.

• Moved FAQ content (“How do I get my podcast featured on Pocket Casts?”, “How do I submit private and paid podcast feeds?”) into a dedicated “Frequently Asked Questions” section in both readme.txt and README.md for better visibility and easier access. [1] [2] [3]

Security and support information:

• Added instructions on how to report security bugs via the Patchstack Vulnerability Disclosure Program to both documentation files. [1] [2]
• Clarified support level and technical requirements, such as PHP version and RSS feed prerequisites, in the documentation. [1] [2]

Minor formatting and consistency fixes:

• Standardized section headings throughout readme.txt for easier navigation and improved readability. [1] [2]
