Invalid character '/' for PATH_SEGMENT in "/notify.png"

[guqing]

What happened?

当 logo 的路径以 / 开头时会出现如标题所述异常，应该是由于 #5148 改动所致

问题出现在：

halo/application/src/main/java/run/halo/app/core/extension/reconciler/PluginReconciler.java

Lines 250 to 255 in 22104fe

	// indicate the logo is a path
	logo = UriComponentsBuilder.newInstance()
	.pathSegment("plugins", pluginName, "assets", specLogo)
	.queryParam("version", pluginVersion)
	.build(true)
	.toString();

这里需要确认一下 logo 的规则：

1. HTTP URL. e.g.: https://www.halo.run/logo.
2. Relative Path to resources folder. e.g.: /logo.png, logo.png
3. Image data URL. e.g.: data:image/png;xxx
