relativeLinkResolution migration

The default value for relativeLinkResolution is changing from 'legacy' to 'corrected'. This migration updates RouterModule configurations that use the default value to now specifically use 'legacy' to prevent breakages when updating.

Before

import { NgModule } from '@angular/core';
import { RouterModule } from '@angular/router';

@NgModule({
  imports: [
    RouterModule.forRoot(ROUTES),
  ]
})
export class AppModule {
}

After

import { NgModule } from '@angular/core';
import { RouterModule } from '@angular/router';

@NgModule({
  imports: [
    RouterModule.forRoot(ROUTES, {relativeLinkResolution: 'legacy'}),
  ]
})
export class AppModule {
}
