Remove Pandoc and LaTeX from www-gitlab-com image

With https://gitlab.com/gitlab-com/www-gitlab-com/-/merge_requests/81890
the last usage of pandoc / LaTeX was removed from the www-gitlab-com
repo. This happened more than 2 months ago, so removing it from the
image should be rather safe, especially considering we use merge trains.

It reduces the image size by around 500 MB.
