Trac #33883: Typo in Steenrod module thematic tutorial

We replace the incorrect `ker(f)` by `ker(q)` here:
{{{#!diff
 which means that the indeterminacy of choosing a lift for
 `f \in \operatorname{Hom}_A(L, Hko)` is represented by an element in
-`\operatorname{Hom}_A(L,\ker(f))`.  Therefore, we can proceed to count
the
+`\operatorname{Hom}_A(L,\ker(q))`.  Therefore, we can proceed to count
the
 number of lifts by computing this vector space of homomorphisms::
