Codemods are not included in ra-core v5

[slax57]

What you were expecting: To be able to run the command

npx jscodeshift ./src/ \
    --extensions=ts,tsx \
    --parser=tsx \
    --transform=./node_modules/ra-core/codemods/replace-Admin-history.ts

As described in the upgrade guide.

npx jscodeshift ./src/ \
    --extensions=ts,tsx \
    --parser=tsx \
    --transform=./node_modules/ra-core/codemods/replace-Admin-history.ts
