fix: align mail icon in buttons properly

Remove align-middle from Mail icon in BaseLink component to fix misalignment 
in buttons. The parent Button component already uses items-center for proper 
vertical centering, and align-middle was causing conflicts.

Fixes the "Get in touch" button icon alignment issue on enterprise page.
