Describe the bug

While capitalise-enum-members (with an s) works as described, the alternative spelling, capitalize-enum-members (with a z), is completely ignored when it is specified in a pyproject.toml file. It is not even validated, so even setting it to a non-boolean value does not cause a validation error. Thus, using this option (with a z) does not produce enum member names in all caps. Note, however, that when the alternative spelling is given directly on the command line, it works as expected. Specifying it in pyproject.toml does not work as expected.

To Reproduce

In pyproject.toml:

[tool.datamodel-codegen]
capitalize-enum-members = true

Used commandline:

$ datamodel-codegen --url https://cdn.earthdata.nasa.gov/umm/granule/v1.6.6/umm-g-json-schema.json

Expected behavior

Enum member names should be in all caps.
