CI, BENCH: asv/seaborn conflict in CI

[tylerjereddy]

Noticed this in gh-971; log is: https://github.com/darshan-hpc/darshan/actions/runs/7508377198/job/20443721367?pr=971

Upstream report/query is here: airspeed-velocity/asv#1363

A temporary pin that worked for me locally to fix it is:

--- a/darshan-util/pydarshan/benchmarks/asv.conf.json
+++ b/darshan-util/pydarshan/benchmarks/asv.conf.json

         "cffi": [],
         "pytest": [],
+        "seaborn": ["0.13.0"],
     },

Perhaps either seaborn or asv needs to change their module naming.

Ah, good catch. I was sidetracked by other issues in my original PR that I hadn't noticed this. I will try to apply this workaround for the time being to get CI back on the right track. Thanks!
