[PATCH net-next] net_shaper: fix net_shaper_ops kernel-doc

[Karl Mehltretter <kmehltretter@gmail.com>]

Everything from the "Driver ops vs uAPI" heading onward is dropped from
the rendered net_shaper_ops documentation. Older Docutils versions do so
silently, while Docutils 0.22 reports the nested headings and adjacent
list as invalid.

Use bold labels and correct the list indentation.

Fixes: 16812d9674d4 ("net_shaper: remove incorrect comment about group leaves")
Fixes: 26bc4cfb1737 ("net_shaper: clarify the kernel API / comments")
Assisted-by: Codex:gpt-5.6-sol

The omission is visible in the current linux-next generated documentation:
https://www.kernel.org/doc/html/next/networking/kapi.html#c.net_shaper_ops

Tested with Sphinx 9.1.0 and Docutils 0.22.4:
  make SPHINXDIRS=networking htmldocs

+ * **Driver ops vs uAPI**
+ *
  * Members of the driver ops mirror the Netlink uAPI but driver calls do not
  * map 1:1 to user calls. Drivers need to be careful when assuming that calls
  * disallowed at the uAPI level will never be made at the driver level.
  * The shaper core performs automatic reparenting and cleanup, generating
  * additional calls. Notably:
- *  - @group calls in the driver facing API may have nodes as leaves (user is
- *    only allowed to construct groups with queues as leaves)
- *  - @group calls may update leaf's parent if the parent is about
- *    to be removed (re-parenting nodes explicitly is not supported in the uAPI)
  *
- * Implicit creation

  * Shapers are created implicitly, meaning that @set and @group operations
  * are called both for existing and new shapers. The driver has to infer
  * whether the operation is an update or a creation by tracking the handles.
