Add LINDI example to streaming documentation

[AtomicGlance]

This adds LINDI to the streaming tutorial so users can open a remote NWB file through an h5py-compatible interface and PyNWB without downloading the complete HDF5 file.

What changed:

• add a project-style LINDI example using LindiH5pyFile.from_hdf5_file and NWBHDF5IO
• show optional local caching and how to open a reusable .lindi.json reference
• add LINDI to the stream and documentation dependency groups so the gallery environment can build the example

The example uses context managers and keeps the existing lazy-slicing behavior clear for readers.

Closes #2170

Validation:

• Python syntax compilation of docs/gallery/advanced_io/streaming.py
• TOML parsing of pyproject.toml
• ruff check --no-cache docs/gallery/advanced_io/streaming.py
• git diff --check
