[PATCH v4 1/2] docs: tracing: Reduce maxdepth in index.rst for clarity

[Purva Yeshi]

Reduce :maxdepth: from 2 to 1 in index.rst to simplify the table of
contents, showing only top-level document titles for better readability.

V4 - Reorder patches to apply the 'maxdepth' change first, then refactor
the index documentation to avoid introducing maxdepth: 2 only to modify
it in the next patch.

+
+Tracing in the Linux kernel is a powerful mechanism that allows
+developers and system administrators to analyze and debug system
+behavior. This guide provides documentation on various tracing
+frameworks and tools available in the Linux kernel.
+
+Introduction to Tracing
+-----------------------
+
+This section provides an overview of Linux tracing mechanisms
+and debugging approaches.

+Core Tracing Frameworks
+-----------------------
+
+The following are the primary tracing frameworks integrated into
+the Linux kernel.

Hi Jon,

It seems like this series didn't make it to 6.15 merge window. What about
applying it on current cycle (for 6.16) instead? Or should I carry and resubmit
it?

Thanks.
