[deps] bump minimum core packages to 7.3.0 to adopt theme color manipulator

[siriwatknp]

To unblock mui/material-ui#47765

As discussed, MUI X v9 is compatible with Material UI v7 and v9.
This PR bumps the minimum version of Material UI and system to ^v7.3.0 for all packages to adopt theme.alpha() to get rid of the direct import of color manipulation.

The benefit is to let Material UI handles the color manipulation based on the theme config.

LGTM. 👌
I've tested Pickers and Tree View, all instances look the same, I assume the result for Data Grid, Charts and Scheduler is the same. 🙌

Nitpick: Is the dep bump agreed upon among the Product people?
We wanted to drop v5 dep for v8, but at the last minute, we had to back-track the change. 🙈
