fix(devtools): remove property tab css that is hiding directive metadata (angular#59493)

It looks like this height property was redundant prior to upgrading to angular/material 19.1.0-rc.0. An interaction between this property and that update caused elements inside of material expansion panels to be hidden.

This PR removes this unnecessary height assignment entirely.
