Fix: Release workflow permissions

[onkarvhanumante]

Release workflow has check user permission step. To check permission workflow makes call to permission api with repo owner and username as input.

Currently repo owner i.e prebid is used as username to check collaborator permission. However, github.actor i.e user who runs workflow should be used to check user permission. PR makes changes to use github.actor as username.

Earlier this workflow was tested on fork repository (https://github.com/onkarvhanumante/prebid-server/actions/runs/7842711148). However on fork repository, value for owner and username were same. Therefore this issue was not seen on fork repository.

Tested new changes on fork - https://github.com/onkarvhanumante/prebid-server/actions/runs/7913227266/job/21600444085

Should this line for the publish-tag step be if: contains(inputs.debug, 'false') similar to the publish-docker-image and publish-release steps? When I go to run the release, the checkbox says: "executes the workflow in debug mode (skip the publishing tag, docker image and release steps)".

[onkarvhanumante]

Publish-tag step has following code. If inputs.debug is true then publish-tag step simply prints the version of next tag but does not create tag. This was done because in debug mode we want to run tests against code and then check what will be next version but don't want to release it.

prebid-server/.github/workflows/release.yml

Lines 108 to 114 in 79ae58d

	if [ ${{ inputs.debug }} == 'true' ]; then
	echo "running workflow in debug mode, next ${releaseType} tag: ${nextTag}"
	else
	git tag $nextTag
	git push origin $nextTag
	echo "tag=${nextTag}" >> $GITHUB_OUTPUT
	fi
