Removing github deprecation warnings

[germa89]

As the title.

This will fix main of the warnings but:

• the GA add_label will run still on Node12. Until PR Bump node12 to node16 in actions.yml actions-ecosystem/action-add-labels#434 is not merged, we cannot update it.
• The zip action has been linked to main branch instead of releases. For now it is ok, but eventually we should change it back to releases/tags. Update action to use NodeJS 16 vimtor/action-zip#20

Related to #1565
