fix: Correct "Recent Activity" preview number

[rschristian]

Why:

Closes: N/A

These docs list the limit of "Recent Activity" entries to be 12, when it's been vastly reduced to 4 for a fairly long while now. The following is my own recent activity:

Limited to 4 entries, with no way to expand to more.

What's being changed:

Just a single number in the content.

Check off the following:

• I have reviewed my changes in staging (look for "Automatically generated comment" and click Modified to view your latest changes).
• For content changes, I have completed the self-review checklist.
