Fix incorrect translation key for parameter_not_allowed.detail

Problem

The gem is looking for the translation key parameters_not_allowed.detail (plural), but the key is correctly defined as parameter_not_allowed.detail (singular) in the code. Because of this mismatch, the translation is not found, and the default English message is shown.

Code with the Issue

Here’s the problematic code:

title: I18n.translate('jsonapi-resources.exceptions.parameters_not_allowed.detail',
                       default: "#{param} is not allowed.", param: param)

Expected Behavior

The code should look for the translation key parameter_not_allowed.detail (singular), as this is the correct key defined in the translation files. For example:

title: I18n.translate('jsonapi-resources.exceptions.parameter_not_allowed.detail',
                       default: "#{param} is not allowed.", param: param)

Solution

Update the code to use the correct translation key: parameter_not_allowed.detail (singular), ensuring it matches the key defined in the translation files.

Start at the I18n.translate call shown in the issue and compare its lookup key with the singular key in the translation files. Done means the exception resolves the defined parameter_not_allowed.detail translation instead of falling back to the default English message; no specific file or test is named.
