Rationale for this change

The link from the datafusion docs to the paper "Encapsulation of parallelism in the Volcano query processing system" was broken.

What changes are included in this PR?

This PR changes the link from https://w6113.github.io/files/papers/volcanoparallelism-89.pdf (which is broken) to https://doi.org/10.1145/93605.98720 (which should "never" break).

A free PDF is available at the new link.

The Volcano paper is cited twice in the datafusion codebase. PR #14497 fixed one of the two citations. This new PR fixes the other citation 🙂.

(There's a slightly higher quality scan of this paper here. But I'd suggest keeping the "official" Digital Object Identifier (DOI) link in the code, because the DOI link should last "for ever".)
