Left sidebar icon is oversized — could it match the right sidebar icon style

Hey Brave team!

Small UI polish suggestion: the left sidebar toggle icon in the toolbar looks oversized and heavier compared to the other toolbar icons (back, forward, reload, reader, bookmark).

Interestingly, the right-side sidebar icon (near the hamburger menu) is already nicely sized and matches the rest of the UI perfectly. Could the left one be updated to match that same style and proportions? Would make the toolbar feel much more consistent.

Thanks
