Update the node version and GH actions in workflows

[broccolinisoup]

Closes #946

Octicons are failed to be publish to NPM due to an error while fetching the docker image to build nodes.

Apparently Debian 9/stretch moved to archive.debian.org (reference)

Found through this thread: https://unix.stackexchange.com/questions/743839/apt-get-update-failed-to-fetch-debian-amd64-packages-while-building-dockerfile-f

Also updating all other node versions and GH actions.

I think we should use node 18 to match Primer React: https://github.com/primer/react/blob/332a1af7d1e961e90a6be198b5b238d843dfad3d/.github/workflows/deploy_preview.yml#L28

Suggested change

	FROM node:20-slim
	FROM node:18-slim

I think we should also update the node-version in these workflows:

https://github.com/primer/octicons/blob/main/.github/workflows/publish.yml#L12

octicons/.github/workflows/release.yml

Line 24 in 4f0c6b4

node-version: 14.x

octicons/.github/workflows/ci.yml

Line 15 in 4f0c6b4

node-version: 14

Thanks @colebemis! I updated all node versions and also the github actions (like checkout, setup-node etc) from v2 to v3
