Proposed Changes

With this PR, some tweaks are made to the 'stop all' button's styles, to ensure it remains visually pleasing with long translations.

Breakdown of the code changes:

• e9caaa0: Removes shrink-0 to ensure the button's content can overflow onto a new line. (Note, this class was first added in 49d1c37 but no longer seems necessary following 756a223.)
• bc24777: Aligns the button's contents to the right. Without this, longer translations appeared to be 'floating' in a way that didn't seem right to me, but I'm open to hearing different perspectives.

Testing Instructions

• Set locale to a language with longer translations, such as Polish.
• Start the server for at least one site within the Studio app.
• Observe the 'Stop all' button and confirm it looks visually pleasing.
