List of valid metrics for structure contains duplicate key missing out cumCasesByPublishDateRate

[OllieCrook]

I know this is the SDK but there is nowhere to comment on the gov.uk docs.

Link to the docs: https://coronavirus.data.gov.uk/details/developers-guide#structure-metrics

Docs show:
cumCasesBySpecimenDateRate Rate of cumulative cases by publish date per 100k resident population
cumCasesBySpecimenDateRate Rate of cumulative cases by specimen date per 100k resident population

Should be:
cumCasesByPublishDateRate Rate of cumulative cases by publish date per 100k resident population
cumCasesBySpecimenDateRate Rate of cumulative cases by specimen date per 100k resident population
