feat: change default value for exclude argument (#514)

The national 10m satellite imagery mosaic has had a name change since
the source imagery was published to the ODR.
Previously it was named `nz_satellite_2021-2022_10m_RGB` in the basemaps
aerial config
It is now named `new-zealand_2022-2023_10m`. This new name structure
will continue going forward.
