Add optional title and update nyc_buildings

[maximlt]

This PR adds the possibility to define a title for a project when the prettified project name is not satisfying, e.g. Nyc Buildings instead of the preferred NYC Buildings.

It also updates nyc_buildings as an example usage of this new functionality.

I've built the docs locally and saw a couple of annoying issues.

• The docs are rendered with all the intermediate states of the ProgressBar.
  

Not sure where this problem comes from. We could work around it by simply removing the ProgressBar but it would at least be good to identify where it's from. It might be from executablebooks/MyST-NB#440 (that was fixing displaying HoloViews objects in mystnb 🙃 )

myst-nb                   0.17.1                   pypi_0    pypi
myst-parser               0.18.1                   pypi_0    pypi
pydata-sphinx-theme       0.9.0              pyhd8ed1ab_1    conda-forge
sphinx                    5.3.0                    pypi_0    pypi

• There are many of this warning that I didn't see in the notebook while running it:

/Users/mliquet/work/dev/examples/nyc_buildings/envs/default/lib/python3.9/site-packages/holoviews/operation/datashader.py:1482: UserWarning: rename 'x' to 'x' does not create an index anymore. Try using swap_dims instead or use set_index after rename to create an indexed coordinate.
  agg = agg.rename({'x': xdim.name, 'y': ydim.name})
/Users/mliquet/work/dev/examples/nyc_buildings/envs/default/lib/python3.9/site-packages/holoviews/operation/datashader.py:1482: UserWarning: rename 'y' to 'y' does not create an index anymore. Try using swap_dims instead or use set_index after rename to create an indexed coordinate.
  agg = agg.rename({'x': xdim.name, 'y': ydim.name})

It seems to me these warnings were removed in holoviz/holoviews#5470 and that the env I used to build the notebook had the latest version of HoloViews (1.15.4). Not sure where they're coming from.

• And the tests failed, while they ran fine on my Mac, with an error raised from SpatialPandas:

 File ~/work/examples/examples/nyc_buildings/envs/test/lib/python3.9/site-packages/spatialpandas/io/parquet.py:350, in _perform_read_parquet_dask(paths, columns, filesystem, load_divisions, geometry, bounds, categories, storage_options, engine_kwargs)
    347 pieces = []
    348 for dataset in datasets:
    349     # Perform natural sort on pieces so that "part.10" comes after "part.2"
--> 350     dataset_pieces = sorted(dataset.fragments, key=lambda piece: natural_sort_key(piece.path))
    351     pieces.extend(dataset_pieces)
    353 delayed_partitions = [
    354     delayed(read_parquet)(
    355         piece.path,
   (...)
    361     for piece in pieces
    362 ]

AttributeError: '_ParquetDatasetV2' object has no attribute 'fragments'
