解决 [WARNING]: Console output during zsh initialization detected.
配置zsh的p10k主题后，报错：
[WARNING]: Console output during zsh initialization detected.
When using Powerlevel10k with instant prompt, console output during zsh
initialization may indicate issues.
You can:
- Recommended: Change ~/.zshrc so that it does not perform console I/O
after the instant prompt preamble. See the link below for details.
* You will not see this error message again.
* Zsh will start quickly and prompt will update smoothly.
解决方法：关闭instant prompt mode。
具体步骤：
p10k configure
到下面这一步的时候选择Off，也可能会叫transient prompt mode
