Missing parent: inconsistent parentage in RNA processing branch

[ValWood]

rRNA modification/tNRA modification are under RNA processing
snRNA modification is not under snRNA processing

• GO term ID and label for which you request a new superclass

• New superclass (parent) suggested

• Reference(s), if appropriate

Also - processing should not be under 'catabolic process'
It should mean biosynthetic process/maturation. But we need to check that the annotations are consistent with this.

Thanks, Pascale

Note the catabolism problem was due to a logical def issue and only appeared recently. Was dealt with in
#27633

Note that the modification terms have logical defs but the ones which are correctly positioned under their RNA processing
terms have this relation instantiated so I have done the same for snoRNA. Maybe one day the "RNA modification" terms will go, but this makes everything in the correct place.
