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

[Purva Yeshi <purvayeshi550@gmail.com>]

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.
