[PATCH v1] docs/arch: remove deprecated function name

[Jiayuan Chen <mrpre@163.com>]

The dumpstack.c file has undergone many modifications, and the
print_context_stack() function was removed or rewritten a long time ago,
so it's better to remove the incorrect guidance. Additionally, no new
functions will be added to the documentation, as it may be modified again
in the future. Using 'question mark' and 'dumpstack' is sufficient to
index this document.
