Update cell_by_location.rq

[dosumis]

Updating to be more generic.

My aim is a generic cells by type/location query. The default option with no location does depend on all cell types being part of some anatomical entity though. I think would be OK to add this at the root of CL. Note that bodily fluids and excreta are anatomical entities (Can add that request to CL).

I fixed a typo and made a query suggestion.

#+ description: Args: cell: the iri or a cell type; location: the iri of an anatomical location. All args are optional. With no args returns all cells with an anatomical location. Location is a union of part_of (suitable for location of most cells) and has_soma_location (used for neurons). This pattern is designed for safe grouping of cell annotations. Returns: a 2 column table: cell (type) IRIs and cell (type) labels.
