Change how goto_beginning, goto_top handle scrolling

[7415963987456321]

Similar to the issue in #1039 but not quite the same since this PR only affects the commands.
Currently when navigating to the top/bottom of the page using keyboard or entering command, sioyek will scroll past the page edge, I found this bothersome and I see no benefit to scrolling past the page like that.

• This changes the way sioyek handles going to the top and bottom of the page with gg and G, or goto_end and goto_beginning commands.
  • Scrolling to the top with gg/ goto_beginning will now stop the page absolutely at the top of the screen
  • Similarly when scrolling to the bottom with G, goto_end, the page will not scroll past the bottom edge
• Changed the way numer repeats offsets the page,
  • Ex. 0gg is equivalent to gg, 1gg is one page from the top i.e. page 2, 2gg is page 3 ... e.t.c
  • Same for scrolling to bottom, 0G is same as G, 1G is next to last page e.t.c
• Fix the 'begining' typo in some functions

Did not occur to me to check the development branch, at a quick glance it seems like these changes have not yet been implemented on there, will rebase these changes onto developer and test further.

Hope this PR gets merged. I also find it annoying how the gg the G commands scroll past the edge of the page.

However, I don't think it's a good idea to change how number repeats offsets the page. Having e.g. 2gg navigate to page 3 doesn't make sense. In my head 2gg translates to "go to page 2", and should go to page 2, not 3. The same principle is true in vim; 10gg will navigate to line 10, not line 11.

Good point, don't generally use that feature of vim, or sioyek for that matter, just had a look at how vim is handling this, and I agree that this PR should behave the same way. Will revisit this at a later date when I have the time.
