(feat): presets

[flying-sheep]

• Closes Add Seurat compatibility preset #3609
• Tests included or not required because:

• Release notes not necessary because:

Self-documenting presets work!

E.g.:

• code:

  scanpy/src/scanpy/_settings.py

  Lines 90 to 96 in 3bae7ae

  	@_preset_property("flavor")
  	def highly_variable_genes() -> Mapping[Preset, HVGFlavor]:
  	"""Flavor for :func:`~scanpy.pp.highly_variable_genes`."""
  	return {
  	Preset.ScanpyV1: "seurat",
  	Preset.SeuratV5: "seurat_v3",
  	}

• docs: https://icb-scanpy--3653.com.readthedocs.build/en/3653/generated/scanpy.Preset.highly_variable_genes.html

TODO

• actually add everything to SeuratV5 flavor
