@babel/plugin-proposal-private-property-in-object is not in required deps

[MocioF]

I have just built 22.9.0 to test an update the gentoo ebuild,
While building, yarn blames about @babel/plugin-proposal-private-property-in-object is not in required deps.

Expected behavior

No warning displayed on yarn build.

Actual behavior

Creating an optimized production build...
One of your dependencies, babel-preset-react-app, is importing the
"@babel/plugin-proposal-private-property-in-object" package without
declaring it in its dependencies. This is currently working because
"@babel/plugin-proposal-private-property-in-object" is already in your
node_modules folder for unrelated reasons, but it may break at any time.

babel-preset-react-app is part of the create-react-app project, which
is not maintianed anymore. It is thus unlikely that this bug will
ever be fixed. Add "@babel/plugin-proposal-private-property-in-object" to
your devDependencies to work around this error. This will make this message
go away.
