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

This would also need documentation to be updated with new option and some tests.

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

I have not looked properly at the changes yet because many tests are failing.

[Renhor]

Corrected the code that was causing the tests to crash
