Shortcuts: Require modifier key to trigger shortcuts (F,A,D,S,T,/)

[cdedreuille]

Closes #16022

What I did

In this PR I'm modifying the default shortcuts to avoid having shortcuts being triggered unintentionally. I added Alt before the first 6 shortcuts transforming from S to Alt + S.

I also replaced / for search into command + K as we are exploring updating our search into a command palette and command + k is a well known shortcut for that.

Code looks good, but it needs a migration note.

[cdedreuille]

@JReinhold I updated the shortcuts to use Alt instead of command for most of them except for search that will stay as command + K` to match what others are doing with their command action. I also added migration guides as you suggested.

[cdedreuille]

It seems we have flaky E2E tests. Since all other tests passed, we discussed this with @JReinhold and he gave me approval to merge this PR directly since the E2E bug is very unlikely related to this issue.

Hello @cdedreuille,
These changes broke some of our Test Cases since the shortcuts keys have changed.
I checked the documentation if there is any way these shortcuts are configurable, but I can't find anything.
Is there any way I can revert them to the values of Storybook 7? Thanks!
