doc/RCU/Design: Remove remaining HTML tags in ReST files
Commit ccc9971e2147 ("docs: rcu: convert some articles from html to
ReST") has converted a few of html RCU docs into ReST files, but a few
of html tags which not supported on rst is remaining. This commit
converts those to ReST appropriate alternatives.
