feat: add possibility to disable default redirect for prefix_and_default strategy

[Renhor]

Regarding to issue #1401

Added property to config:

i18n: {
  disableDefaultRedirect: boolean | string[] // false by default
}

It works only for strategy prefix_and_default. It disables redirect for routes are prefixed with default language, or we can choose custom path pattern for disabling redirect behaviour:

i18n: {
  disableDefaultRedirect: [
    '/about',
    '/blog/*'
  ]
}

UPD:

Added property to config:

type PrefixAndDefaultRule = 'default' | 'prefix'

i18n: {
  prefixAndDefaultRule?: PrefixAndDefaultRule
}

By setting the value prefixAndDefaultRule = 'prefix' we are no longer redirected from prefixed routes and if there is no prefix then the other routers will also have no prefix.

For now, I decided not to implement an array with a list of routes for which the default behavior is disabled

rchl Thanks for the quick review. Unfortunately, I will only be able to continue working on the task today. I decided to abandon the route array and changed the implementation following your advice. Updated the information in the first post

Corrected the code that was causing the tests to crash
