Description:

The 2.3.1 update (#1960) removed several documentation items from the Docs folder that should be restored:

• alttester-editor.md: removed Show Native Popup Option setting
• alttester-with-appium.md: removed Selenium/WebGL section, connection settings popup section, and all Appium/Selenium code examples
• _static/examples~/appium/ and _static/examples~/selenium/: all example files deleted (C#, Java, Python, Robot)
• Screenshots updated to no longer reflect the native popup option in the editor
