I thought I had fixed this already once but it still looks broken.
Basically when hovering over main menu buttons every now and then it
will look like their backgrounds are not covering their entire width
when they expand.
The removed X position set looks wrong to me when inspecting the draw
visualiser with the element because the element looks to be off centre
horizontally, and removing it fixes that.
(Or local date, in the case of non-deployed builds).
Came up when I was looking at https://github.com/ppy/osu-web/pull/11240
and found that we were still hardcoding this.
Thankfully, this *should not* cause issues, since there don't seem to be
any (documented or undocumented) API response version checks for
versions newer than 20220705 in osu-web master.
For clarity and possible debugging needs, the API response version is
also logged.
