[PATCH v2] docs: symbol-namespaces: fix reST warning with literal block

[Khaled Elnaggar <khaledelnaggarlinux@gmail.com>]

Use a literal block for the EXPORT_SYMBOL_GPL_FOR_MODULES() example to
avoid a Docutils warning about unmatched '*'. This ensures correct rendering
and keeps the source readable.

Warning:
Documentation/core-api/symbol-namespaces.rst:90: WARNING: Inline emphasis start-string without end-string. [docutils]

Changes in v2:
- Use 'For example::' to create a literal block, suggested by Matthew Wilcox.
