Node 16 Deprecation

[kinano]

Node16 will be deprecated on 09/11/2023 (link).

Node 16 is used by the action at the moment according to the source code:

github-action-slack-notify-build/action.yml

Lines 26 to 27 in 3665186

	runs:
	using: 'node16'

Is there a plan to release a node version update soon?

We are maintaining a version at https://github.com/zuplo/github-action-slack-notify-build that is node 20 compatible.
