📚 Description

This change modifies the locale method to provide a default locale if none is specified. Previously, if the locale parameter was omitted, it would result in an undefined value being passed to the I18n instance. By using locale || this.defaultLocale, we ensure that the default locale is used, improving usability.

I think this PR changes the behavior of the locale method. Instead of making the first parameter as required, we are making it optional. Any reasons, you want to make the parameter optional?

Hello @thetutlage,

Currently, to use i18n, we need to do something like:

const i18n = i18nManager.locale(i18nManager.defaultLocale)
const subject = i18n.t('messages.email_confirmation_subject')

I think const i18n = i18nManager.locale() would be a cleaner code style.

Another suggestion is to provide a simpler way to use i18n, such as:

const { t } = i18nManager.default()
const subject = t('messages.email_confirmation_subject')

Alright, makes sense!
