Replace deprecated set-output in GitHub actions

[curquiza]

In our GitHub actions, we are using set-output command which is deprecated and will be removed.

See this link for example

We need to replace with environment variables, following this GitHub article: https://github.blog/changelog/2022-10-11-github-actions-deprecating-save-state-and-set-output-commands/

🔥 Should be done by the end of May 2023 🔥

Hello @SO-HYBE

Thanks for your interest in this project 🔥 You are definitely more than welcome to open a PR for this!

For your information, we prefer not assigning people to our issues because sometimes people ask to be assigned and never come back, which discourages the volunteer contributors from opening a PR to fix this issue.
We will accept and merge the first PR that fixes correctly and well implements the issue following our contributing guidelines.

We are looking forward to reviewing your PR 😊

Ok I got your point. Let's do it

@SO-HYBE Hi. I don't see any opened PR from you. Are you still with this? Or may I take over?

@curquiza Hi there.
I have made the change to the workflows according to the presented documentation. You could find my change here
However, I am not able to trigger any workflow for testing, as it keeps Waiting for a runner to pick up this job...
Do you have any suggestion on the testing for this issue?

Hello @pnhatminh can you open a PR so that I can review and merge it? 😊 The changes you made seem ok
