Browse source 
Fix `WebDriverScriptCommand::GetElementText` similar to
https://github.com/servo/servo/pull/37452#discussion_r2146350739, by
correctly retrieving rendered text.

Testing: `./mach test-wpt -r --log-raw "D:\servo test
log\gt_ele_txt.txt" webdriver/tests/classic/get_element_text --product
servodriver`
