Replace deprecated command with environment file

[jongwooo]

Description

Update workflows to use environment file instead of deprecated set-output command.
For more information, see: https://github.blog/changelog/2022-10-11-github-actions-deprecating-save-state-and-set-output-commands/

I found the workflow files that use set-output command through the following command:

$ find . -name '*.yml' -o -name '*.yaml' | xargs egrep '\bset-output\b'

AS-IS

echo ::set-output name=BRANCH::$(echo ${BRANCH} | cut -d '.' -f1-2 | tr -d 'v')

TO-BE

echo "BRANCH=$(echo ${BRANCH} | cut -d '.' -f1-2 | tr -d 'v')" >> $GITHUB_OUTPUT
