Maintenance: remove Gitpod-specific dev files

[dreamorosi]

Summary

Gitpod now supports the devcontainer.json specification, which means we no longer need to maintain two separate configurations for Gitpod & GitHub CodeSpaces.

We should remove the .gitpod.yml & .gitpod.Dockerfile files.

Why is this needed?

So that we can streamline our maintenance burden.

Which area does this relate to?
