fix: icon and description for expand/collapse all items in keyboard shorcuts dialog

[bonsak]

Description

1. This pull request fixes the description of keyboard shortcut for expand / collapse of navigator items. The working shortcut for expand/collapse navigator items are alt + click on both osx and windows. But is listed in the Keyboard shortcuts dialog as ⌘ + click on osx and CTRL + click on windows.
2. This PR also changes the description of the shortcut to be more inline with other shortcuts for navigator items.

Steps for reproduction

1. Open any project
2. Open the Keyboard shortcuts menu

• On OSX, the expand / collapse navigator items is listed as ⌘ + click
• On WIN, the shortcut is listed as CTRL + click

Code Review

• hi @kof, I need you to do
  • conceptual review (architecture, feature-correctness)
  • detailed review (read every line)
  • test it on preview

Before requesting a review

• made a self-review
• added inline comments where things may be not obvious (the "why", not "what")

Before merging

• tested locally and on preview environment (preview dev login: 0000)
• updated test cases document
• added tests
• if any new env variables are added, added them to .env file

I don't know why the Lost Pixel tests are failing. Any pointers on how i can fix this PR so it might pass these tests?

Edit made. Lost pixel checks are still failing. Not sure how to solve this.
