Fix: Support link padding

[Takshil-Kunadia]

Description

Fixes the Support link/button having incorrect padding on plugin pages.

Trac Ticket: https://meta.trac.wordpress.org/ticket/8147

Problem

The "Support" link on plugin pages (e.g., https://wordpress.org/plugins/sync-content-from-notion) had asymmetric padding, with the right padding missing. This caused the active state to appear visually unbalanced.

Before	After

Tested on a plugin page and confirmed the Support link padding looks consistent in the active state now.

Minor suggestion: the padding could be simplified to padding: 0.64rem 1.25rem; for readability (same computed values).

Thanks @manhphuc for looking into this. Made the change. ✅

As this dates back to http://meta.trac.wordpress.org/changeset/5399 I feel like this is intentional.

While the screenshot above clearly shows the padding would be better equal, it's not in the context of the greater page, the purple box added clear shows that the text is right aligned; except the visual download button which is aligned with the text indented like a button should be. The support link is a link, and not a button.
