changes: enable total count meta on get

[chemitaxis]

This PR solves #527

I have added a new optional parameter on options to enable add metadata, it looks like:

{
      jsonapi: { version: '1.1' },
      links: {
        self: 'http://localhost/api/user',
        first: 'http://localhost/api/user?page%5Blimit%5D=5',
        last: 'http://localhost/api/user?page%5Boffset%5D=0',
        prev: null,
        next: null
      },
      data: [
        {
          type: 'user',
          id: 'user1',
          attributes: [Object],
          links: [Object],
          relationships: [Object]
        },
        {
          type: 'user',
          id: 'user2',
          attributes: [Object],
          links: [Object],
          relationships: [Object]
        }
      ],
      meta: { total: 2 }
    }

Thanks a lot for the contribution @chemitaxis !

Btw, there're conflicts in the pnpm-lock.yaml file, I guess cause by the latest changes in the "dev" branch and also a mismatch in the pnpm version. You can just revert the changes to that file and the CI should pass then.

Thanks! Looking good now. I'll merge when I get back to my laptop. It'll be included in the next release landing in a day or two.
