[spp] [PATCH 2/2] docs: update link of command reference

[ogawa.yasufumi at lab.ntt.co.jp]

From: Yasufumi Ogawa <ogawa.yasufumi at lab.ntt.co.jp>

In 'How to Use' section, link for SPP command reference refers to
the url of readthedocs. However, it might be changed in future.
This update is to change the link from url to relative path to avoid
not found error.
