feat(dashboard, medusa, medusa-js, medusa-react, icons): DataGrid, partial Product domain, and ProductVariant hook (#6428)

The PR for the Products section is growing quite large, so I would like to merge this PR that contains a lot of the ground work before moving onto finalizing the rest of the domain.

**Note**
Since the PR contains changes to the core, that the dashboard depends on, the staging env will not work. To preview this PR, you will need to run it locally. 

## `@medusajs/medusa`

**What**
- Adds missing query params to `GET /admin/products/:id/variants`
- `options.values` has been added to the default relations of admin product endpoints.

## `medusa-react`

**What**
- Adds missing hook for `GET /admin/products/:id/variants`

## `@medusajs/dashboard`
- Adds base implementation for `DataGrid` component (formerly `BulkEditor`) (WIP)
- Adds `/products` overview page
- Adds partial `/products/create` page for creating new products (WIP - need to go over design w/ Ludvig before continuing)
- Adds `/products/:id` details page
- Adds `/products/:id/gallery` page for inspecting a products images in fullscreen.
- Adds `/products/:id/edit` page for editing the general information of a product
- Adds `/products/:id/attributes` page for editing the attributes information of a product
- Adds `/products/:id/sales-channels` page for editing which sales channels a product is available in
- Fixes a bug in `DataTable` where a table with two fixed columns would not display correctly

For the review its not important to test the DataGrid, as it is still WIP, and I need to go through some minor changes to the behaviour with Ludvig, as virtualizing it adds some constraints.

## `@medusajs/icons`

**What**
- Pulls latest icons from Figma

## TODO in next PR
- [ ] Fix the typing of POST /admin/products/:id as it is currently not possible to delete any of the nullable fields once they have been added. Be aware of this when reviewing this PR.
- [ ] Wrap up `/products/create` page
- [ ] Add `/products/:id/media` page for managing media associated with the product.
- [ ] Add `/products/id/options` for managing product options (need Ludvig to rethink this as the current API is very limited and we can implement the current design as is.)
- [ ] Add `/products/:id/variants/:id` page for editing a variant. (Possibly concat all of these into one BulkEditor page?)
