Make the manage tags of project have more convenient functions(groups,edit,change color)

[Milo-o-Fun]

（English）
Using the latest godot4.3, unexpectedly found a good function of project manage tags, but the actual use found that it can be further optimized.

1. Grouping function: Labels can be divided into different levels.
   For example," Game "," Tools "," Web "is a type partitioning," in development "," testing "," finished "," abandoned" is a state partitioning, but the labels in the current version are unexpectedly messy and slightly confusing when tagged.
2. Modification function: We should add text modification and color modification to make it more in line with user-defined needs.
   During the exploration, it was found that the way to modify (or rather, delete) an existing label is to leave all items unlit and then restart the editor, which is very tedious, and the uncontrollability of the label color is not conducive to user habit, so as to make faster use of color pleasant discrimination (although this is optional, but especially useful in large notes).

在使用最新的godot4.3引擎中,意外发现好用的项目标签管理功能,但实际使用后发现其实可以进一步优化。
1.分组功能: 实际使用标签场景标签可以分成不同的层次。
例如"游戏","工具","网页"是一种类型分法,"开发中","测试中","已完成","已放弃"是一种状态分发,但是当前版本中的标签意外的混乱,在标记时稍显混乱。
2.修改功能: 应该添加文本修改,颜色修改使得更符合用户自定义需要。
在探索中,发现修改(或者准确的说,删除)一个已有标签的方法是将所有的项目不点亮该标签,然后重启编辑器,这显得非常繁琐,而且标签颜色的不可控不利于用户习惯便于更快利用颜色愉快的辨别(虽然这一项可有可无,但在巨量便签中特别有用)

Colors are intentionally hardcoded to ensure different projects using the same tag always use the same color for that tag. It would look confusing otherwise. See the initial implementation for details.

For example," Game "," Tools "," Web "is a type partitioning," in development "," testing "," finished "," abandoned" is a state partitioning, but the labels in the current version are unexpectedly messy and slightly confusing when tagged.

I think showing the project version (the application/config/version project setting) could be done in the project manager, but I wouldn't encourage adding tags that refer to a specific development state.
