It's probably infringement, but there is an argument to be made that it simply recites facts and facts aren't protected by copyright. In general, copying-pasting someone's words is prima facie infringement if you ignore the defense of fair use. The question then lists the factors involved in fair use - quoting the entirety, it's not criticism of the original work, nor transformative, etc.
HOWEVER,17 U.S.C. ยงยง 101 "Subject matter of copyright" states:
(b) In no case does copyright protection for an original work of
authorship extend to any idea, procedure, process, system, method of
operation, concept, principle, or discovery, regardless of the form in
which it is described, explained, illustrated, or embodied in such
work.
Feist Publications, Inc. v. Rural Telephone Service Co., Inc. further clarifies this.
To understand the potential debate:
Consider a love song. The fact that Taylor Swift loves Travis Kelce isn't copyright-protected. The wording she uses to express that in a song is what's protected, the lyrics she uses. The same applies here. The facts of how it's done aren't eligible for copyright. The technical writer's work in skillfully and clearly explaining it produces wording which may be protected by copyright.
This particular example is a bit of a gray area - the facts aren't copyright protected and there would be a question of "how many different ways are there to say it?"
In Feist, SCOTUS ruled that even a recitation of facts can be protected if there is an element of creativity, stating compilations of facts may be protected if the expression "entail[s] a minimal degree of creativity, are sufficiently original"
See also Harper & Row.
I would say it's (barely) copyright infringement; other knowledgeable people may go the other way. It would likely hinge on the question of what level of creativity and skill went into choosing that wording.
Note - the question points out attribution. In the United States, the attribution mostly doesn't matter. It can be one factor in fair use, but you said "ignoring fair use".
