mac os support for additional key-combos for changing tabs

[milezhacks]

Summary

TIL KeePassXC does support option-tab for changing tabs but the cmd-shift-[] and/or ctrl-pgup/dn (which work in every other multi-document application I can think of including browsers and vscode) would be nice too

Examples

Try cmd-shift-[ and cmd-shift-] in Chrome. 👍
Try cmd-shift-[ and cmd-shift-] in VSCode. 👍
Try cmd-shift-[ and cmd-shift-] in XCode. 👍
Try cmd-shift-[ and cmd-shift-] in KeePassXC 👎

Context

Minor tweak which would improve UX by using familiar key combos.

The tab switching key combos are generally provided out of the box by Qt but we introduced a couple others.

Qt defines

Next tab: Ctrl+}, Forward, Ctrl+Tab
Prev tab: Ctrl+{, Back, Ctrl+Shift+Tab
