feat(i18n): allow custom interpolation options for i18n

[zleight1]

Allow for specifying custom interpolation options for i18n. This is useful for custom interpolation patterns, such as {{ and }}. Tests added, and scoped to the i18n module.

Closes #4726

🔎 Overview

Adds the ability to use custom interpolation options, such as prefix and suffix.

This allows the library to comply with the default i18next standard.

  generateMessage: localize(
    'en',
    {
      messages: {
        between: 'The {{field}} field must be between 0:{{min}} and 1:{{max}}',
      },
    },
    {
      prefix: '{{',
      suffix: '}}',
    },
  ),
});
