Fix interval keyword argument in oedi_9068 gallery example

[karlhillx]

Fixes #2791.

Problem

The oedi_9068 gallery example calls get_nsrdb_psm4_conus() with interval=5, but the function's parameter is named time_step. The interval name comes from the NSRDB API query string, not the Python signature — the docstring even notes "Called interval in NSRDB API."

This was missed when PR #2582 migrated the example from get_psm3 (which used interval) to get_nsrdb_psm4_conus (which uses time_step). The maintainer confirmed the fix in #2791.

Fix

Changes interval=5 to time_step=5 in the example call (one line).

Tests

No test changes needed — test_get_nsrdb_psm4_conus_5min in tests/iotools/test_psm4.py already exercises time_step=5 against the function directly. The bug was in the gallery example, not the function.

Thanks @cwhanse! Applied both Copilot suggestions (PSM3→PSM4 narrative + variable rename) and added myself to Contributors in v0.15.3.rst.

Re: the failing test_singlediode_precision[2-lambertw] check — this change only touches the oedi_9068 gallery example (docs), so that failure appears unrelated. Happy to look into it separately if you'd like.
