After starting with 'emacs -Q', I tried to do the above test with the
guidance here [1] to install auctex:

M-x package-install RET auctex RET

But I meet the following:

Install package: auctex RET

no match

OTOH, the following method works as described here [2]:

1.2 Installing AUCTeX

The modern and strongly recommended way of installing AUCTeX is by
using the Emacs package manager integrated in Emacs 24 and greater
(ELPA). Simply do M-x list-packages <RET>, mark the auctex package for
installation with i, and hit x to execute the installation procedure.
That’s all.

Any then, I use a minimal tex file:

\documentclass{article}
\begin{document}
Hello world.
\end{document}

After opening the above file, eval the following setting:

M-: (setq LaTeX-electric-left-right-brace t) RET

Then, I observed the same effect as shown be you.
