This pull request adds keyboard shortcut support for starring or unstarring commits, making it easier for users to interact with commit cards using the keyboard. The main changes include passing a shortcut prop to the CommitStarButton, updating tooltip and accessibility attributes, and documenting the shortcut in the keyboard shortcuts dialog.

Keyboard shortcut integration:

• Added a keyShortcut prop (set to "s") to the CommitStarButton component in commit-card.tsx, enabling the "s" key to star or unstar the focused commit. [1] [2] [3]
• Updated the CommitStarButton to use the keyShortcut prop for tooltip display and accessibility, including setting the aria-keyshortcuts attribute and showing the shortcut in the tooltip.

Documentation and discoverability:

• Added the "s" key shortcut to the keyboard shortcuts dialog, describing its use for starring or unstarring the focused commit.
