Fix mui theme to use version 7

Fixed #4538 to switch `@rjsf/mui` theme to use MUI v7
- Updated `@rjsf/mui` to use v7, switching from `Grid2` to `Grid` and using `slotProps` in `BaseInputTemplate`
  - Updated the snapshots accordingly
- Also updated all of the `README.md` files for the themes to update versions for dependencies
- For `fluentui-rc` and `daisyui` themes, moved the theme engine dependencies to `peerDependencies` and `devDependencies`
- Updated `@rjsf/semantic-ui` to deprecate the theme
- Ran `npm update` to get the latest versions of libraries, causing `antd` snapshots to be updated
- Updated the `v6.x upgrade guide.md` to reflect the MUI upgrade and deprecation of `semantic-ui`
