Fix open in browser shortcut using wrong action name

[tux3]

I noticed that the open page in browser shortcut had not worked for me in a long time. I compared to the code for open history in browser (which does work), and found that the actionOpen_page_in_browser was not connected to anything.

The right handler seems to be on_actionOpen_in_a_browser_triggered, which is a slightly different name for the same action.

There is also on_actionDisplay_this_page_in_browser_triggered, which is yet another one. I'm not sure I know what the difference is between these two, but this patch is enough to fix the disconnected "O" shortcut.

(The IDE also wanted to strip a couple trailing spaces while saving the file)

Hello, I will have a look into this but I just used Huggle recently and I remember I was using O shortcut extensively and it worked just fine. Were you trying latest release?

so I did a quick code check and it seems that - Open page in a browser is indeed disconnected from everything, Open in a browser is hard-wired to O shortcut via the .ui file? Need to double check on it

If I recall correctly the difference between these 2 is that Open page should open the page eg. for [[test]] it would go to /wiki/test, while just Open in browser opens whatever is being rendered, most likely a diff itself in the browser.

Definitely needs some cleanup

Could this be a Qt5/Qt6 difference? I build from source with Qt6, but I do remember it working fine in the past (and when I ran a Git blame on these lines, the last changes were from 2014, so how it worked in the past/was supposed to work I don't fully understand yet)
