* Force convert to JPG for preview card thumbnails to avoid animations

Fix #7093

KeyboardEvent.key may be physical key name (Escape, Tab, etc.)
even in text composition and it causes hotkeys or suggestion selection.
So we need to check e.which or e.isComposing.

Checking e.which also allows us to avoid Esc key on compositionend in Safari.

Fix the hot key (j, k) does not function correctly when there is a pinned toot in account timeline. (#7202)

* Run yarn manage:translations and update Japanese translations.

This fixes following cases which causes hotkey action accidentally:

  Although events on cancelling composition are still heavily
  browser / input method dependent, but this implementation would
  covers current UI Events spec and some exceptions.

This PR changes to use keydown event instead of keyup event as well as other hotkeys.
