[FEATURE REQUEST] Allow video speed change in 5% increments instead of 10%

[Kacperrk]

Currently, the video speed can only be adjusted in 10% increments, which limits flexibility. For example, it's not possible to set the video speed to exactly 1.25x - users must settle for 1.20x or 1.30x instead.

It would be great if the speed adjustment could be adjusted in 5% increments, giving users more options for precise playback speed.
