Possibly incorrect `self` link on `collections/<collection-id>/items` page

[TomAugspurger]

Spotted by @geospatial-jeff, the "self" link at https://planetarycomputer.microsoft.com/api/stac/v1/collections/sentinel-2-l2a/items?limit=1 links to the collection "https://planetarycomputer.microsoft.com/api/stac/v1/collections/sentinel-2-l2a".

❯ curl --silent 'https://planetarycomputer.microsoft.com/api/stac/v1/collections/sentinel-2-l2a/items?limit=1' | jq .links[3]
{
  "rel": "self",
  "type": "application/json",
  "href": "https://planetarycomputer.microsoft.com/api/stac/v1/collections/sentinel-2-l2a"
}

Should that instead be the URL itself, like https://planetarycomputer.microsoft.com/api/stac/v1/collections/sentinel-2-l2a/items?limit=1?
