[Go/zh-cn] Update the Simple Chinese Version of Golang

• I solemnly swear that this is all original content of which I am the original author
• Pull request title is prepended with [language/lang-code] (example [python/fr] for Python in French or [java] for multiple Java translations)
• Pull request touches only one file (or a set of logically related files with similar changes made)
• Content changes are aimed at intermediate to experienced programmers (this is a poor format for explaining fundamental programming concepts)
• If you've changed any part of the YAML Frontmatter, make sure it is formatted according to CONTRIBUTING.md

Description of the changes

• Remove an analogy of Java
  • The original content is 类似java中的塑型, which means similar to 塑形 in java. But there is no terminology called 塑形 in Java.
• Correct an analogy of Java
  • The original content is 类似java中的序列化, which means similar to serialization in java. But serialization is a very abstract and more complex concept. The toString() method in Java is closer to the example String().
• Fix a wrong translation
  • The original translation 用make来声明一个slice means use make to declare a slice. This doesn't explain the example correctly and is not the same with the English version Same make function used earlier to make a slice.
  • The new translation means Initialize a slice with make as in the previous example, which removes ambiguity.

我搜了一下，好像有 塑形 这种说法，不过感觉现在一般就说 类型转换 了

哦，我搜错了，搜成 塑形 了。搜索 塑型 确实能够搜到，确实表达的是 类型转换 的意思，不过不是什么官方术语。那我把原来这个类比加回来好了，改成 类型转换。
