fix(core): improve pinned tasks annotation on narrow width (#31175)

This is intended to be a super quick improvement until I can work on
something a bit more substantial.

## Current Behavior
<!-- This is the behavior we have today -->

We always try and render `[Pinned output {}]`.

## Expected Behavior
<!-- This is the behavior we should expect with the changes in this PR
-->

We only render `[{}]` on narrow widths.

## Related Issue(s)
<!-- Please link the issue being fixed so it gets closed when this is
merged. -->
