fix(browser): change default wait_until from load to domcontentloaded

Updated the default wait_until parameter from 'load' to 'domcontentloaded'
for browser navigation functions to improve performance and reduce waiting time
for full page loads when not necessary.

This change affects browser_navigate_back and browser_go_forward functions
in the BrowserToolSet class to use 'domcontentloaded' as the default
waiting strategy instead of 'load'.

将默认的 wait_until 参数从 'load' 更改为 'domcontentloaded'

更新了浏览器导航函数的默认 wait_until 参数，从 'load' 改为 'domcontentloaded'
以提高性能并减少不必要的完整页面加载等待时间。

此更改影响 BrowserToolSet 类中的 browser_navigate_back 和
browser_go_forward 函数，使用 'domcontentloaded' 作为默认等待策略
而不是 'load'。
