Closes #5033: intermittent arkouda_makefile test failures

[ajpotts]

Summary

This PR re-enables the install-pytables step in GitHub Actions CI and updates the PyTables dependency Makefile to install from a fixed upstream tag (rather than an arbitrary repo head).

Motivation

• CI previously skipped PyTables installation (step was commented out), which reduced coverage for any code paths depending on PyTables/HDF5.
• The existing pytables.mk logic cloned the PyTables repo but did not pin a version, and also mixed Make directives inside a shell recipe, which is brittle.
• Pinning to a tag makes builds reproducible while still using the same “clone + local install” mechanism.

Changes

• CI: Un-commented and restored the Make install-pytables step, with retries, and passing HDF5_DIR to ensure the local HDF5 install is used.
• Makefile (make/deps/pytables.mk):
  • Added PYTABLES_VERSION, PYTABLES_TAG, and PYTABLES_DIR.
  • Replaced the non-functional ifeq-inside-recipe block with a POSIX shell if check.
  • Fetches tags and checks out v$(PYTABLES_VERSION) before updating submodules.
  • Installs via pip install ./PyTables from the checked-out working tree.

Version pinned

• PyTables v3.11.1 (via PYTABLES_VERSION ?= 3.11.1).

Testing

• CI should now exercise the PyTables install step again.
• Locally: run make install-hdf5 install-pytables DEP_BUILD_DIR=... (ensure HDF5_DIR is set as in CI).

Notes

If a newer PyTables release is desired later, bump PYTABLES_VERSION in make/deps/pytables.mk.
