fix(db-postgres): create relationship-v2-v3 migration (#9178)

### What?
This command from here:
#6339
```sh
payload migrate:create --file @payloadcms/db-postgres/relationships-v2-v3
```
stopped working after db-postgers and drizzle packages were separated 

### How?
Passes correct `dirname` to `getPredefinedMigration`

Additionally, adds support for `.js` files in `getPredefinedMigration`
