Update High-Visibility Pages

Issue

Several of the highest-visibility pages of the FreeSWITCH™️ documentation have broken links, outdated information, and references to previous wiki systems. For instance:

• docs/FreeSWITCH-Explained/index.mdx
• docs/FreeSWITCH-Explained/Introduction/index.mdx
• docs/FreeSWITCH-Explained/Community/index.mdx

Solution

Updating these pages.
