remove an extra dash from numpy.org website's title "NumPy - "

[partev]

current Numpy.org's website title is "NumPy - "

It is not clear what the purpose of the extra dash is. It feels like something else, like a short description of NumPy was meant to follow after the dash but is somehow missing. I suggest either removing the dash, or adding a short description after the dash.

I think this comes from the scientific-python hugo theme, from here

 <title>{{ block "title" . }}{{ .Site.Title }}{{ if not (eq .Site.Title .Title) }} - {{ .Title }}{{end}}{{ end }}</title>

Perhaps the main page does not have a .Title attribute. @stefanv thoughts?
