Fix overflow issue with share playlist icon drop-down (#4677)

* Set share playlist dropdown position to `center` w/ media query

* Remove overflow-y as it causes the overflow issue

Originally, when this overflow-y was added, the share playlist dropdown went straight down, so there would no need for the content to be able to overflow in the y direction. (FreeTubeApp/FreeTube#2281)

Now, the dropdown swings out to the left by default, and even when it is centered, it still overflows the width of the container as an intentional part of the design.

* Remove unnecessary whitespace
