fix: remove deprecated expandconverter

The expandconverter is deprecated as of 0.107.0 and leaving it enabled causes
issues with the parsing of environment variables. For example, when supplying an
identifier like '1234' to a string field through an environment variable, this
would incorrectly be treated as an integer and fail validation.
