Feature: Support vue template in sidebar

[2jun0]

Summary

Bugfix

• If section name is weird just like --, dom.find('#--') cause error. so, It has to be changed. 7060fcc

changed const section = dom.find('#' + id);
to const section = dom.find(`[id='${id}']`);

• When only using {{ 1 + 1 }} syntax, It doesn't necessarily have to exists vueGlobalOptions and vueComponents. c24a7f7

I removed the sentence below so that we can use vue into simple template(such as {{ 1+1}} without vueGlobalOptions or vueComponentName, etc....
if (docsifyConfig.vueGlobalOptions || vueComponentNames.length)

New Feature

• Support vue template in sidebar. 14cf646

Previously, when the title of the markup document uses vue, there was an error that did not apply to sidebar.

# TEST

## Hello World!

## {{ message }} 

## {{ "re:" + message }}

@2jun0 sorry we hadn't gotten to this. Thank you for the idea. We're working on simplifying and modernizing things. Eventually I'd like to make it possible to swap Docsify templates entirely, which would allow anything like sidebars with Vue, React, Svelte, etc.
