Remove deprecated ESMPy regridding schemes

[bouweandela]

Description

Remove deprecated ESMPy regridding schemes ESMPyAreaWeighted, ESMPyLinear, and ESMPyNearest.

Upgrade instructions

In most cases, users do not need to do anything as the default regridding schemes have been updated so these schemes are no longer used.

If you were using these schemes from Python or through a Generic regridding scheme in your recipe, you will need to update it to use esmvalcore.regrid_schemes.IrisESMFRegrid instead.

do we still need esmpy as dep then? Thanks, buds 🍺

[bouweandela]

Not directly, only through iris-esmf-regrid. I removed it in eb1f34c

ah after esmpy gave me half a head of white hairs when supporting Python 3.13, it finally gone - not gonna miss it 😁
