[PATCH] docs: redirect from old arch to the new one

Due to a recent reorganization of 'CPU Architectures', the links to
the documentation from external resources were rendered invalid.
This is a common challenge when attempting to make changes
while maintaining backward compatibility. To address this issue,
a commit has been made which uses sphinx extension to seamlessly
redirect users from the old location of the page to the new one.
