Wrong extra index url for pypi

[IvanLipetsk]

Hi!
I guess --extra-index-url here:

gitea/templates/package/content/pypi.tmpl

Line 7 in a36951a

<div class="markup"><pre class="code-block"><code>pip install --index-url <origin-url data-url="{{AppSubUrl}}/api/packages/{{.PackageDescriptor.Owner.Name}}/pypi/simple/"></origin-url> --extra-index-url https://pypi.org/ {{.PackageDescriptor.Package.Name}}</code></pre></div>

suppose to be https://pypi.org/simple instead of https://pypi.org/
