fix: sync the page title regarding the title config

[Koooooo-7]

Summary

Currently, on the v5 changes, each headings/links on the sidebar has the title via #addTextAsTitleAttribute.

docsify/src/core/render/index.js

Line 20 in 42f2548

#addTextAsTitleAttribute(cssSelector) {

After the event refactor, the page title update function changed, especially the search page title.

Example from our site.
v4:
On the main content load the page title such as Configuration, no matter you switch the sections to Configuration.
or directly jump to its sub headings configuration?id=alias.

The page title is always `Configuration`.

v5 as-is:
On the main content load the page title such as Configuration, switch the sections to Configuration. (same to v4 )
⚠️ directly jump to its sub headings configuration?id=alias via the URL，it will update the page title to sub title (alias) instead.
⚠️ On the search function, when clicks the search result, it comes to the mess innerText as page title instead.

The behavior for the sidebar headings for main content, I think it makes sense to indicate the specific target and respect the title.
So, I fix the search problem via a consistent way that all retrieve page title from to the title attribute also.
Now, it will use the ${name} - ${title} as the page title, if no name config, use title directly.

Hmm, I see yeah it is inconsistent depending how you land on the page. Clicking on your link, the title is alias, but if you navigate to the page from inside Docsify, the title is Configuration.

Also I think that it would be better for the title to be Docsify - Page for each page whre Page is the name of the page, or similar. F.e. Docsify - Configuration, Docsify - Quick start, etc.

Yea, It makes sense that we could concat the name of the site as a prefix. I gonna update it.

Since the name configuration can "also contain custom HTML for easier customization" (due to its primary/first use in the sidebar) using the name for page title generation can produce some ugly results.

I liked @Koooooo-7 recommendation to make a pageTitleFormatter config option.
