[codegen] Update node version management

[joeblubaugh]

The out-of-the-box boilerplate doesn't manage node versions. I get this error with make build/plugin-frontend:

error [email protected]: The engine "node" is incompatible with this module. Expected version ">= 18". Got "16.17.0"
error Found incompatible module.

This could be improved with a .nvmrc file that specifies the minimum version supported by the dependency graph.

There is one of these, just at a different level of the directory hierarchy than I was looking. The actual issue appears to be that the default generated dependencies and the nvmrc aren't compatible.
