@backstage/migrate-mui-switch-to-bui-switch

Migrates MUI 4 Switch usage to Backstage UI Switch.

Covers

• Named barrel and deep @material-ui/core/Switch imports
• FormControlLabel wrapping Switch → BUI Switch with label
• disabled → isDisabled, checked → isSelected, defaultChecked → defaultSelected
• Merging into an existing @backstage/ui import

TODOs left for humans

• Non-string FormControlLabel labels
• Unsupported MUI Switch props (color, size, edge, classes, …)

Won't do

• Non-Switch FormControlLabel controls (handled by radio/checkbox codemod)
