doc: revert anachronistic 'node:' module require()s in API history notes

Support for the 'node:' prefixed builtin module namespace was introduced
for `require()` expressions in Node v16.0.0, and backported to v14.18.0.
This was never supported in Node v15.x or chronologically older.

All of the current API history notes in the docs using 'node:' prefixed
module `require()`s happen to be documenting changes in Node versions
from before the time when support was first introduced.

This commit reverts those `require()`s in the history notes to be
un-prefixed. (They were incorrect as written; The prefixed `require()`s
would not work for those older Node versions.)

This change prevents the API history notes from inaccurately implying
'node:' prefixed builtin modules were introduced many Node versions ago,
or were `require()`-able with the 'node:' prefix in those Node versions.
