Nearly completely replace the original GitHub actions workflow.
Changes:
- Move from `.sh` files in `ci/steps` to steps in the workflow.
- Move from using docker images for environment to manual setup.
- Upgrade nfpm to v2.3.1
BREAKING CHANGE: official arm64 builds no longer support CentOS 7.
If you need to use CentOS 7 on arm64, build `code-server` locally.
For docs, see the yarn/npm section in `docs/install.md`.
native-keymap and keytar are only used in the electron process,
so we don't need them. This allows us to drop our dependencies on
libx11-dev, libxkbfile-dev, and libsecret-dev.
We only want to use an old version for glibc which the centos:7
image takes care of.
The old version of git used in debian:8 was causing problems
with the uid/gid passthrough with no user in passwd.
