Describe your changes

• This PR is to update labeler workflow (automate labeling PRs)
  • https://github.com/actions/labeler#create-workflow
• The labeler workflow has been disabled to check a security issue within the labeler workflow. (a high level permission given to the pull_request_target option)
• According to some valuable discussions with @yunkon-kim , we concluded that the concern with the permission issue can be minimized. (please review and discuss if there is any other concern)

PTAL @yunkon-kim

[yunkon-kim]

@seokho-son I have a simple suggestion as follows :-)

[jihoon-seo]

Amending to @yunkon-kim's suggestion:

Suggested change

	- pull_request_target
	pull_request_target:
	types: [opened, synchronize]
	paths:
	- 'content/**.md'
	branches:
	- 'dev-**'
	- 'main'

If we add 'main' as target branch, then this will automatically label lang/en for the PRs that add/modify 'content/en/**.md' and target main!

(Ref: https://docs.github.com/en/actions/using-workflows/events-that-trigger-workflows#running-your-workflow-based-on-the-head-or-base-branch-of-a-pull-request-1)

---

For information:
The default value of sync-labels is false. (https://github.com/actions/labeler#inputs)
We might need to add action.yml to this repo and set the value of sync-labels to true,
to make synchronize-related thing work.

@jihoon-seo thanks for your updates!

I agree that main is a vital point in this workflow.

For a simple discussion:
I was thinking about the synchronize type. However, I couldn't find any cases of reassigning the label when synchronizing.

Also, when we add the synchronize type, this workflow will be triggered by every PR synchronization.

Therefore, it would be nice to add the 'synchronize' as needed.

If anyone has a case that synchronize is necessary, please feel free to share.

[seokho-son]

I removed "synchronize" for this time. Let's see it is necessary after some period. :)

@seokho-son

main was not added to the branches section. Is it ok?

[seokho-son]

@yunkon-kim Added :)

[jihoon-seo]

LGTM!

@seokho-son
I think we should enable the "pull Request Labeler" workflow =)
