Subject: [PATCH] When querying for terms, do not assume that `$taxonomies` is
 a 0-indexed array.

In [25108], the logic of term queries was modified to avoid assuming
that the `taxonomies` array was numerically indexed. See #23506. This
fix was inadvertantly reverted during the refactor in [25162].

Props david.binda.
Fixes #41113.
