doc: Fix a symbol issue

[vxzyfx]

Motivation

There is a punctuation error.

Solution

Change “socket hijacking” to "socket hijacking".

punctuation error

Just a nit, but the currently used quotation marks are known as smart quotes. Given that the comment is written in English prose, I wouldn't say they are erroneously used from a typographical perspective (albeit it's rare to see them actually typed out, given that they are non-trivial to type on a QWERTY keyboard). So the question of whether one should use smart quotes or non-smart quotes here boils down to a matter of taste—rather than right or wrong—IMO.

Thank you for your explanation.
