CI actions failing due to h5py error

[carns]

(As noted by @wkliao in #1035 )

Some of our CI actions are failing due to problems installing h5py, see example in https://github.com/darshan-hpc/darshan/actions/runs/15542212610/job/43755427619?pr=1035 .

This looks to me to be related to this issue reported (and closed) on the h5py repo: h5py/h5py#2579

Is the problem in our case also that we are using an older setuptools that isn't compatible with this syntax?

Ah, scrolling up a little further in that example CI failure, it does look like it is using an old setuptools:

 Collecting setuptools<62.0.0
  Downloading setuptools-61.3.1-py3-none-any.whl.metadata (6.0 kB)

I'm not sure what's controlling that.

Seems like pinning setuptools version was a workaround again for an h5py related issue #896 . As @wkliao suggested in #1041 , removing this specific version should solve this issue.

Good find @orcunyildiz , its good to know why the version was pinned (and why its safe to use a newer version now). I went ahead and merged @wkliao 's fix.
