Front Matter 中 Copyright 设置出现问题

[guanqr]

设置 original = false，然后自定义作者 author，如果不添加 website 的内容，作者一栏的冒号 ： 会消失。

如果是下面这样显示正常：

original = false
author = "GitHub"
website = "https://github.com/"
link = "https://github.com/"
copyright = "[CC BY-SA 4.0](https://creativecommons.org/licenses/by-sa/4.0/deed.zh)"

如果是下面这样，会缺少冒号：

original = false
author = "GitHub"
link = "https://github.com/"
copyright = "[CC BY-SA 4.0](https://creativecommons.org/licenses/by-sa/4.0/deed.zh)"

另外更新到 Hugo 0.69.0 版本后，采用 sections 进行文章分类，在分类页面如果设置开启显示每一分类下的文章数，即 displayPostsCount = true，会报错。显示主题中的 tree-sections.html 代码有问题。但在 0.68.3 版本中没有报错，不知道是主题的问题还是 Hugo 的问题。

Error: Error building site: failed to render pages: render of "section" failed: execute of template failed: template: section/categories.html:2:7: executing "main" at <partial "pages/tree-sections.html" .>: error calling partial: "/opt/build/repo/themes/meme/layouts/partials/pages/tree-sections.html:25:79": execute of template failed: template: partials/pages/tree-sections.html:25:79: executing "partials/pages/tree-sections.html" at <len $pages>: error calling len: len of untyped nil

第一个问题已解决。

第二个问题应该是 Hugo 的问题，已提交 Issue，见 gohugoio/hugo#7178

Seems fixed in v0.69.2.
