CI: Run dev tests on Scientific Python nightly wheels

[weiji14]

Description of proposed changes

Check that PyGMT will work on future versions of numpy>=2.0.0, pandas>=2.1.0, xarray>=2023.7.1 and so on.

References:

• Pre-built wheels are at https://anaconda.org/scientific-python-nightly-wheels
• SPEC 4 — Using and Creating Nightly Wheels at https://scientific-python.org/specs/spec-0004

Extends #1105 when pip install --pre started being used. The nightly wheels from https://pypi.anaconda.org/scientific-python-nightly-wheels/simple are a lot more up to date than those on the default PyPI index.

Reminders

• Run make format and make check to make sure the code follows the style guide.
• Add tests for new features or tests that would have caught the bug that you're fixing.
• Add new public functions/methods/classes to doc/api/index.rst.
• Write detailed docstrings for all functions/methods.
• If wrapping a new module, open a 'Wrap new GMT module' issue and submit reasonably-sized PRs.
• If adding new functionality, add an example to docstrings or tutorials.
• Use underscores (not hyphens) in names of Python files and directories.

Slash Commands

You can write slash commands (/command) in the first line of a comment to perform
specific operations. Supported slash commands are:

• /format: automatically format and lint the code
• /test-gmt-dev: run full tests on the latest GMT development version

Nice, no visible deprecation warnings or errors with using the nightly versions of NumPy, Pandas, Xarray, etc 🎉. See https://github.com/GenericMappingTools/pygmt/actions/runs/5594537134/jobs/10229490969?pr=2612#step:16:723
