Cannot delete a field which uses JSON type

Problem/Motivation

When trying to uninstall Experience Builder, it crashes with "Unable to parse the column type JSON".

That's because \Drupal\sqlite\Driver\Database\sqlite\Schema::getFieldTypeMap does not contain a mapping for JSON fields. No other driver errors for this. That's because \Drupal\sqlite\Driver\Database\sqlite\Schema::introspectSchema is SQLite specific.

So when deleting the field it crashes.

Steps to reproduce

Install XB or any field using json type. Try to uninstall or delete field. It crashes

'pgsql_type' => 'jsonb',
          'mysql_type' => 'json',
          'sqlite_type' => 'json',
          'not null' => FALSE,
