Force to use sharp v0.32

[pettinarip]

Running yarn dev crashes because it expects sharp which is not installed since we only installed it on Netlify contexts for reasons explained in #12957.

Description

This fix reverts the changes made in #12957 to install sharp. It now forces the installation of sharp@v0.32.6 as this version does not cause problems with local and netlify envs. sharp is currently installed by @storybook/nextjs.

Consider this a temporary solution until we find a better way to install the latest version and avoid problems with different envs.
