Fix test suite name (#6270)

## Problem
The name of the test suite for grid resizing didn't match the file name
(and actually was the same as another test suite's name), which could
lead to confusion and frustration

## Fix
Change its name to match the file it's in

editor/src/components/canvas/canvas-strategies/strategies/grid-resize-element-strategy.spec.browser2.tsx
