Update github actions for deprecated node 12

[dmijatovic]

The last release action produces number of warnings to be addressed.

See notification https://github.com/research-software-directory/RSD-as-a-service/actions/runs/3345281898

After initial investigation I conclude:

• TriPSs/conventional-changelog-action@v3 is just updated by owner - no action required
• set-output should be updated before 01-06-2023, see info here

# derecated
- name: Set output
  run: echo "::set-output name={name}::{value}"

# use this instead
- name: Set output
  run: echo "{name}={value}" >> $GITHUB_OUTPUT

After initial tests it seems that TriPSs/conventional-changelog-action@v3 depends on @actions/core that also need to update, see issue

Next step

Test these adjustments on the fork and monitor status of @actions/core
