fix: Fix issue with long credential type names (#2961)

* 🐛 Fix issue when saving long credential's types

The column type in the entity credentials was varchar(33) but nodes like Google Cloud Natural Language exceed the type length. The issue in only found when using Postgres. Mysql works fine as the column type has the proper length. Probably a migration at some point did not property update the column.
