fix(docs): align navbar GitHub button height with Sign in button

[Jordy-Baby]

Boxes the navbar GitHub button and pins it to the same height as the Sign in button so the two line up. Matches the boxed GitHub button on envio.dev.

• GitHub button: bordered box, 38px, centred icon
• Sign in: pinned to the same 38px height
• Global navbar, so it applies across every docs page

Verified locally on desktop and mobile (both buttons render at exactly 38px, top/bottom aligned).

Screenshots

Before, bare GitHub icon sitting shorter than the Sign in button.

After, bordered 38px box aligned with Sign in.

Full navbar for context.
