fix: update subheading for clarity and consistency

[d-alleyne]

Fixes #100549

Proposed Changes

Updated the subheading on the /me/purchases page to: "Manage your sites’ plans and upgrades."
This ensures consistency with the "Active Upgrades" tab and improves user understanding.

Why are these changes being made?

The previous subheading, "View, manage, or cancel your plan and other purchases," was inconsistent with the "Active Upgrades" tab and included extraneous actions like "View" and "Cancel." The updated subheading aligns better with the tab's purpose and simplifies the language.

Testing Instructions

• Navigate to /me/purchases in the application.
• Verify that the subheading now reads: "Manage your sites’ plans and upgrades."
• Confirm that the change is reflected across all relevant views and does not introduce any visual or functional regressions.
