Subject: [PATCH] fix(test): assert the default Accept header on the parameters
 fetch
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The release workflow fails on "Resource parameters can be retrieved":

    AssertionError: expected last "spy" call to have been called with
    [ 'http://localhost/books', …(1) ]
    -     "headers": {},
    +     "headers": Headers {},

Two pull requests crossed. #179 added the assertion expecting a plain
"headers: {}", and #178 merged twenty seconds later made setHeaders() always
build a Headers instance carrying the default Accept. Both were green against
main as it stood when each ran, so neither CI saw the other.

Assert what the two changes together are meant to guarantee: the parameters
fetch targets the collection and carries the default Accept header. Comparing
against a Headers instance is not an option, it has no enumerable own
properties and the matcher reports "no visual difference" while failing.
