 * ENV_USED_TOKEN format:
    - `key` - id of the env. At that id the value of the env will be accessible through `environmentManager` and will be loaded from the external sources.
    - `value` - default low-priority value for env `key`
    - `optional` - is current env is optional. If `true` the app can work as usual event if the env value were not provided, if `false` - the app will fail to run without env value
    - `validator` - validation function for passed env value. In case this function returns string it will be used as error message and validation will fail
    - `dehydrate` - if `false` then env value will not be passed to client and this env can be used only on server
 *
 * @example
  ```tsx
  interface EnvParameter {
    key: string;
    value?: string;
    optional?: boolean;
    validator?: (value: string) => boolean | string;
    dehydrate?: boolean;
