Update data provenance

[victorlin]

from #16 (comment)

Pathoplexus is the only data source listed in the Auspice config.

ebola/phylogenetic/defaults/west-africa-2014/auspice_config.json

Lines 6 to 11 in 0dee7a3

	"data_provenance": [
	{
	"name": "Pathoplexus",
	"url": "https://pathoplexus.org"
	}
	],

The workflow has since been updated to include metadata from various sources (GenBank, INRB, fauna). Consider adding entries for those data sources.

For the all-outbreaks config I used

  "data_provenance": [
    {"name": "Pathoplexus", "url": "https://pathoplexus.org"},
    {"name": "INRB (DRC)", "url": "https://github.com/inrb-drc/ebola-nord-kivu"},
    {"name": "GenBank", "url": "https://www.ncbi.nlm.nih.gov/genbank/"}
  ],
