change Ralstonia example genome

[bluegenes]

from discussion w/ TLP:

tl;dr: Yes, it looks like that genome has quality issues. If convenient, you could change it to this strain: IIB-1_UW551_Geranium-Geraniaceae_Kenya_GCF_002251655.1.genome (This is a member of the pandemic lineage and one of the model strains that Ralstonia folks will recognize the UW551 name of)
