Fixing set_stream_quality function

[S1NJED]

I Fixed the set_stream_quality() function that was cuasing errors due to a wrong OR deprecated XPATH.

• I handle the video player element when there is an ad or not.
• I removed the chromedriver.exe (don't need the .exe)
• I removed the fact that it open a page to a proxy but do nothing
• I removed a duplicata of the main function
• I changed the install.bat to create a virtual environment

We don't to download the chromedriver.exe manually.

It work well on my win10 computer and Chrome 119 at 05/11/2023
