Enhance the Release Notes by adding dropdown menus

[jprestop]

Please use Sphinx Design for Dropdown menus . This will allow for searches of material hidden within dropdown menus.

Changes will need to be made to the below files:

1. config.py
   add 'sphinx_design' to the "extensions =" section. (note the underscore.)
2. requirements.rst file.
   add 'sphinx-design==0.3.0' with a dash
3. MET/.github/workflows/documentation.yml
   add a line after this example line 28 . Make sure it is correctly indented.
   python -m pip install -r docs/requirements.txt
4. Remove 'sphinx-panels' from line28 in the code. This was originally added for dropdown menus. But the new version is 'sphinx-design'. It isn't needed. Removing it should avoid future confusion. sphinx-gallery Pillow sphinx_rtd_theme sphinx-panels

It should look like this:
python -m pip install --upgrade python-dateutil requests sphinx
sphinx-gallery Pillow sphinx_rtd_theme
python -m pip install -r docs/requirements.txt

Panel drop downs would be added for the subcategories and sub-subcategories. For example,
-Repository and build
---Installation
---Static Code Analysis
---Testing
---Continuous Integration
-Documentation
-Library code
---Bugfixes
---Python embedding enhancements
---Miscellaneous
---NetCDF Library
---Statistics computations
etc.

Note: One downside to using panels is that the content of the text contained in the panel will not show up in the search. However, I’m not sure the search functionality is particularly important for the Release Notes.

@lisagoodrich and I are reopening this issue because we have one more step that needs to be completed. The build on ReadTheDocs is working fine, but the build in GitHub Actions is not. The GHA run appeared to be successful, but was actually not successful. We are already aware of this problem and it will be fixed with the issue Bugfix: Check the return status of the "make clean html" command in build_documentation.sh #2436.

The following needs to be added to this issue:

MET/.github/workflows/documentation.yml
add a line after these lines 27 and 28. Make sure it is correctly indented.

python -m pip install -r docs/requirements.txt

It should look like this:

          python -m pip install --upgrade python-dateutil requests sphinx \
          sphinx-gallery Pillow sphinx_rtd_theme sphinx-panels
          python -m pip install -r docs/requirements.txt

I have updated the issue information with the steps needed to make sure the dropdown menus run correctly.
