Describe the reason for change

This provides the much needed missing support for going to previous and next tasks using keyboard hotkeys. The current process is impossible to use without a mouse when reviewing already annotated tasks and this pr will allow the re-reviewing process of tasks to be able to be an entire keyboard based operation which significantly speeds up the process

Built and tested it works as expected. Fulfills this request: #2311 (comment)

[Skier23]

Further testing revealed that the next and previous hotkeys when on the review page, aren't going to the expected next and previous images. I'm guessing the previous and next methods are not giving the correct result when in the review window but I don't know the code thoroughly enough to know exactly whats going on.

[Skier23]

I just included an alternate way to do this which is by modifying dm.focus-next and dm.focus-previous to always go to the next/previous item instead of just changing focus to the next/previous item (which seemingly doesn't do anything now). This could be an even simpler way to do this. One potential downside of it though is that approach wouldn't work for going previous and next on tasks when in the label multiple tasks labeling view once this is fixed: #5357 @jombooth

Also that second approach as is (or what was there before it with the selecting) has a bug where it doesnt scroll the page down once it gets passed the choices on the page so it doesnt load new items and eventually can't continue going next because of it. Also if you manually scroll the page down it appears to go back to the first item on the page.

edit: I found the source of that second bug mentioned above. This hack works around it but this is where that bug occurs at:
https://github.com/HumanSignal/label-studio/pull/5350/files#diff-843ceacdc988004db8884789b11629a7f380644a2b587c921f950d15333a3df0

Regarding that first bug, its not too hard to workaround since if you use the previous button, itll go back to the previous one before it resets the page so its not a huge deal. (with the fix/workaround to the second bug)

[Skier23]

I've been reviewing existing annotations on my end using these changes and its been working well btw. (primarily using the focus-next and previous changes). The all-keyboard approach is over 2x as fast when reviewing data for me at least

[Skier23]

@Serhii-beep @jombooth just checking to see about getting this incorporated in some form? I'm still running on my local build of this branch and I can no longer upgrade label studio until this gets incorporated.

No problem. I've pushed changes to address the pr comments and merged and resolved conflicts.

[Skier23]

@juliosgarbi I've rebuilt and tested locally after the changes on my end and after merging with the latest from development and everything works correctly in testing.
