[website] Allow for disabling the "homeScreenFeedTabs" selector

[jamesmunns]

Is your feature request related to a problem? Please describe.

Often, I try to two-finger scroll (Firefox on MacOS) on the feeds list (I think called "homeScreenFeedTabs" from a quick inspect) to pick a different feed, I just trigger "back" in the browser, and I go to another page when I don't expect.

This is easy to trigger if you are already at "one end" of the scroll list, or if you are not actually hovering over the scroll list and still two-finger swipe.

Describe the solution you'd like

I would like to be able to disable the top scroll container of lists, and instead just train my muscle memory to use the bar on the right. This could be a "preferences" configurable that would default to having the top bar enabled.

Describe alternatives you've considered

I could just "get over it", or use some kind of third party scripting tool to hide the element.

Or, Bluesky could use a menu element that doesn't require left/right scrolling.

Additional context

This is the element I'd like to disable:

IMO it is somewhat redundant with this element, at least in cases where by browser window is large enough not to hide it:

As I've used the website more I've come to have the same sentiment. I just don't use the left-right scrolling menu on the website at all. It could free up some space. I'd want to make sure the current feed name is still prominently displayed at the top -- that is important.
