✨ feat: 优化模板编辑体验，支持使用代码块来存储模板语法

Feature or bug? 特性或者缺陷？

关联：#15344

痛点

思源笔记原生没有模板编辑器，模板语法直接粘贴到笔记里，容易渲染成数学公式等样式，无法原样导出到模板，即无法在思源笔记里完成包含模板语法的模板制作

而使用外部编辑器，当创作带有背景颜色、自定义属性以及含有大量列表的模板时，会非常不便，过去经常要先在思源笔记弄好样式，然后导出为模板，再在外部编辑器添加模板语法，替换占位文字

改进
支持使用代码块来存储模板语法：
代码块语言设置为template时，认为是存放模板语法的地方，导出为模板，代码块里的模板内容变为纯文本段落，这样就可以直接导出带有模板语法的模板，就能直接调用，创建模板变得所见即所得

例子，在思源笔记创建如下内容的笔记

导出为模板

我感觉可以给代码块增加一个内置的 siyuan-template 语言（命名参考 php-template）

注册高亮，就会添加语言选项了，至于叫siyuan-template，还是template，D大决定吧（个人觉siyuan-template太长了，不方便打），在思源本体没必要加siyuan，外部软件和网站高亮思源模板才需要加

• 渲染.action 块和{{}}块规则：变量、注释、函数、关键字、字符串、数字
• 渲染Markdown块
• 渲染思源块属性设置语法为注释，对属性名进行高亮

虽然明显偏题，但是我找到highlightjs-solidity 2.0.5->2.0.6，highlightjs-sap-abap 0.2.0->0.3.0，如果D大和V大觉得有必要的话在合并之后看看吧

[88250]

导出模板的 go 代码已经从正则替换改为修改语法树实现了。

辛苦啦，我一开始也是想修改语法树的，但是不熟悉语法树结构，就曲线救国用正则啦

[Achuan-2]

@Vanessa219 我看是直接把siyuan-template别名都删掉了吗，我觉得highlight.js的aliases可以保留下，代码块可以不支持直接选择siyuan-template，但需要siyuan-template的高亮，

后面可以给highlight.js提交pr，支持siyuan-template的高亮

这样后面如果其他外部网站介绍思源模板语法，可以用siyuan-template为代码块语言（用template为代码语言适合思源自己内部用），用思源笔记剪藏文章下来也能直接高亮
