Add missing definitions to dorsal and ventral pancreas

[cindyJax]

Suggested definitions and synonyms for:

UBERON:0009708 dorsal pancreas Def: The transient embryonic structure that fuses with the ventral pancreas during development to form a single organ; the dorsal pancreatic bud gives rise to the body, tail, and isthmus of the pancreas. [PMID:23909279] Synonym: dorsal pancreatic bud

UBERON:0009709 ventral pancreas Def: The transient embryonic structure that fuses with the dorsal pancreas during development to form a single organ; the ventral pancreatic bud gives rise to the pancreatic head and uncinate process. [PMID:23909279] Synonym: ventral pancreatic bud

see also Mammalian Phenotype Ontology tracker requests #2075 and #2076 for more extensive definitions. I recommend making 'dorsal pancreatic bud' and 'ventral pancreatic bud' the preferred label.

note we have bud terms already

• UBERON:0003923 ! dorsal pancreatic bud
• UBERON:0003924 ! ventral pancreatic bud

I think the two classes you mention should be merged into these. It looks like they were put in as an attempt to be consistent with EHDAA2:
