Inconsistency for reference in Synonyns

[floesche]

1. Most citations follow the form "AUTHOR YEAR: SYNONYM". For the Gorko paper, it is instead "SYNONYM, AUTHOR JOURNAL YEAR".
2. Also, there is a typo for 10 of the SNpp17 and SNpp22 neurons: It should be MCN not MNC.
3. One of the SNpp18 is classified as MCN, but should most likely be a LCN.
4. Some of the SNpp18 don't have a synonyms field

I suggest to follow the standard from the other citations and fix inconsistencies on the way. That would require the following changes:

• for 821938, 909271, 902320, 902403, 820181, 819291, 902402, 902397, 1060570389, 1060484465, 829606, 822497, 902357, 817350: synonyms='Gorko 2024: LCN'
• assign LCN instead of MNC [sic] for 908013: synonyms='Gorko 2024: LCN'
• for 905158, 912181, 914370, 907697, 902351, 810452, 802287, 816434, 902352, 902353, 910285, 821279, 823972, 817564: synonyms='Gorko 2024: MCN'
• add synonyms for 816004, 913067, 834000: synonyms='Gorko 2024: LCN'

This was observed in male-cns:v0.9. Initially reported for cns on August 16 in #16
