refactor(install\_software.sh): remove redundant script for recording screen and delete the corresponding file record\_screen.sh

remove the following lines from install\_software.sh:

```bash
ffmpeg -vsync 0 -hwaccel cuda -hwaccel_output_format cuda     `# we need nvidia acceleration because of low fps without it` \
--r 30 -video_size 640x480 -i /dev/video0  `# this is camera` \
--f alsa -i default -async 1                                   `# this is audio. Why not pulse? Nvidia?` \
--c:v h264_nvenc                                     `# this is video codec` \
video.mp4 # output file
```

Also, remove the filter\_complex line and the x11grab section.

This refactoring is done to simplify the script and make it more focused on installing software rather than recording the screen.
