Update tree and blob resolvers to accept ref_type

What does this MR do and why?

Update tree and blob resolvers to accept ref_type

Also propagate ref_type to blob and tree presenters so that routes so frontend code can continue depending on the rendered routes

This is the first of a series of MRs for addressing the issue of not being able to browse files when a tag and branch have the same name.

For context the other MRs:

• Controller changes: !122237 (merged)
• Frontend changes: !122145 (merged)

How to set up and validate locally

1. Create a project with a branch and tag with the same name
2. Try graphql queries to see that the correct blobs and trees are rendered

Example queries

query testPaginatedTree {
  project(fullPath: "root/project-with-branch-and-tag-sharing-name") {
    id
    repository {
      paginatedTree(path: "/", ref: "ambiguous", refType: TAGS) {
        nodes {
          trees {
            nodes {
              id
              sha
              name
              flatPath
              type
              webPath
            }
          }
          blobs {
            nodes {
              id
              sha
              name
              flatPath
              type
              mode
              webPath
              lfsOid
            }
          }
        }
