teams/cloud/container: Add langpacks-en to Toolbx

Fedora Silverblue and Workstation, and so the Kickstart equivalent of
the fedora-toolbox OCI image, contain langpacks-en by default.  It's
absence leads to a significant difference in the list of RPMs, which is
better to avoid so close to the Fedora 40 final release:
  -abattis-cantarell-vf-fonts-0.301-12.fc40.noarch
  -default-fonts-core-sans-4.0-12.fc40.noarch
  -fonts-filesystem-2.0.5-14.fc40.noarch
  -google-noto-fonts-common-20240301-3.fc41.noarch
  -google-noto-sans-mono-vf-fonts-20240301-3.fc41.noarch
  -google-noto-sans-vf-fonts-20240301-3.fc41.noarch
  -google-noto-serif-vf-fonts-20240301-3.fc41.noarch
  -hunspell-1.7.2-7.fc40.x86_64
  -hunspell-en-0.20201207-9.fc40.noarch
  -hunspell-en-GB-0.20201207-9.fc40.noarch
  -hunspell-en-US-0.20201207-9.fc40.noarch
  -hunspell-filesystem-1.7.2-7.fc40.x86_64
  -langpacks-core-en-4.0-12.fc40.noarch
  -langpacks-fonts-en-4.0-12.fc40.noarch
  -liberation-fonts-common-2.1.5-9.fc40.noarch
  -liberation-mono-fonts-2.1.5-9.fc40.noarch
  -liberation-sans-fonts-2.1.5-9.fc40.noarch
  -liberation-serif-fonts-2.1.5-9.fc40.noarch
  -sil-mingzat-fonts-1.100-5.fc40.noarch

The plan is to investigate if Toolbx containers can use some of these
packages from the host.  However, that needs to be co-ordinated with the
toolbox(1) binary, and has to be a done in a way that works across a
wide variety of container and host combinations.

Until then, it's safer to retain the status quo.
