If we remove the documentation, I think we might as well remove the other related files. So could you remove other reference or files related to Dockerfile or Gitpod?

EDIT: Also possibly good timing to remove Gitpod, looks like they're rebranding/refocusing efforts as well https://github.com/gitpod-io/gitpod/blob/main/README.md

@mroeschke should I also remove gitpod/ and Dockerfile or just the related files for this PR?

Yes please. And any files or lines in files that used Dockerfile or anything in gitpod/

(pandas-dev) kev@earth pandas % rg -ie "docker" .
./web/pandas/pdeps/0010-required-pyarrow-dependency.md
189:- Alpine linux (commonly used as a base for Docker containers)

./scripts/tests/data/deps_minimum.toml
149:# the base windows docker image to check if any dlls are

./doc/source/whatsnew/v1.5.0.rst
399:- The ``Dockerfile`` now installs a dedicated ``pandas-dev`` virtual environment for pandas development instead of using the ``base`` environment (:issue:`48427`)
(pandas-dev) kev@earth pandas % rg -ie "gitpod" .
(pandas-dev) kev@earth pandas % ls -R | grep -i "gitpod"
(pandas-dev) kev@earth pandas % ls -R | grep -i "docker"
Dockerfile.pandas-debug

Not sure if I should also delete ./scripts/tests/data/deps_minimum.toml docker part but it looks like its related to windows CI dockerimage.

Dockerfile.pandas-debug is not tracked on git
