🏗 Migrated posts.page column to posts.type (#11111)
refs https://github.com/TryGhost/Ghost/issues/10922

- adds migrations to...
  1. add `post.type` column
  2. populate `post.type` column based on `post.page` value
  3. drop `post.page` column
- updates all code paths to work with `post.type` in place of `post.page`
- adds `nql-map-key-values` transformer for mapping `page`->`type` in `filter` params when using the v2 API
- modifies importer to handle `post.page`->`post.type` transformation when importing older export files

# nql-map-key-values
This utility returns a transformer which can be passed to the `@nexes/nql` library to transform queries
### Usage
```js
const nql = require('@nexes/nql');
const mapKeyValues = require('nql-map-key-values');
nql('good:true', {
transformer: mapKeyValues({
key: {
from: 'good',
to: 'bad'
},
values: [{
from: true,
to: false
}, {
from: false,
to: true
}]
});
}).toJSON(); // => {bad: false}
```
