fix(test): don't use latest sharp

[ForsakenHarmony]

Why?

We use yarn@1 to install test dependencies and sharp@0.33.0 doesn't allow installing the native binaries with yarn@1 for some reason.

See: lovell/sharp#3871

Closes PACK-2058

One note is that sharp@0.33.0 or higher will be desirable for WebAssembly at some point in the future

• Docs: Indicate High memory usage if not installing sharp for image optimization #41417 (comment)

What worked for me with Yarn v1 was installing sharp@0.33.0 using the --ignore-engines flag
