It's documented in
https://www.postgresql.org/docs/current/functions-comparisons.html, and
has been around since at least 7.4.

Well, to be fair, we don't really say anywhere that LIKE acts enough
like a plain operator to be used in this syntax.  And the underlying
code is the subquery_Op production in gram.y, which is specific to
this syntax, so I'm not sure offhand to what extent LIKE acts like
an operator for other corner cases.

Doesn't look to me like subquery_Op has changed much since 2004,
so you'd really need to be more specific.
