Fix aging related trait definitions

[rays22]

GO editors think that the process of aging GO:0007568 is a phenotype: [The reason for obsoletion is that this represents a phenotype.] (https://github.com/geneontology/go-announcements/issues/502) There are several traits, phenotypes and diseases that are related to the process of ageing/aging. I would live happily without ageing, but I need to fix the definitions of some ageing-related OBA terms:

entity_attribute.tsv
2736:OBA:0003870                GO:0007568      aging   PATO:0002325    onset quality
3652:OBA:0005494                GO:0007568      aging   PATO:0000161    rate

Shall I create new PATO quality terms for these?

1. aging onset quality
2. aging rate

I can use the new PATO terms this way:

2736:OBA:0003870                NCBITaxon:131567      cellular organisms   PATO:???????    aging onset quality
3652:OBA:0005494                GO:NCBITaxon:131567      cellular organisms   PATO:???????    aging rate
