Temporarily publish a `gts` tag for F38

[castrojo]

Ok so F39 is pushed to 7 November - we were hoping to use the offline ISO that defaults to gts.

We need to launch everything (not just the ISO, there's associated website, docs stuff) before 4 November since that's Kubecon.

• Shipping the ISO with :latest as F39 is the least desirable
• Shipping a :38 is also not desirable because people will have to remember to rebase.
• Ideally some kind of temporary tag solution so we can generate an ISO with gts that points to 38, and then when F39 comes out we transparently set it up "normal".

Temporary moving this gts if out of here, so it wouldn't have to wait on f39 getting the latest tag. So we can get a live gts tag already. And revert this when f39 gets the latest tag.

          if [[ "${{ matrix.is_latest_version }}" == "true" ]] && \
             [[ "${{ matrix.is_stable_version }}" == "true" ]]; then
              BUILD_TAGS+=("latest")
          elif [[ "${{ matrix.is_gts_version }}" == "true" ]]; then
              BUILD_TAGS+=("gts")
          fi

          if [[ "${{ matrix.is_latest_version }}" == "true" ]] && \
             [[ "${{ matrix.is_stable_version }}" == "true" ]]; then
              BUILD_TAGS+=("latest")
          fi
          if [[ "${{ matrix.is_gts_version }}" == "true" ]]; then
              BUILD_TAGS+=("gts")
          fi

Oh also, would we need to touch any of the other images? (hoping for a no!)
