Radix dialog does not work well with other libraries components

[igorlesnenko]

See: https://github.com/ParabolInc/parabol/pull/8696/files#r1297499570

I had to use the old modal instead of the radix one as the radix one wouldn't let me select any of the datetime fields.

I tried updating the z-index in a few different places, and spent a fair amount of time looking into it, but the original modal works with the MUI datepicker so I think it's best to use that.
