[Dev] Make PRs that doesn't match our PR format draft automatically

Describe the enhancement requested

We have a CI job that checks our PR format:

Lines 63 to 72 in 6378639

    
                 - name: Check title 
        
                   if: | 
        
                     (github.event.action == 'opened' || 
        
                      github.event.action == 'edited') 
        
                   uses: actions/github-script@v9 
        
                   with: 
        
                     github-token: ${{ secrets.GITHUB_TOKEN }} 
        
                     script: | 
        
                       const script = require(`${process.env.GITHUB_WORKSPACE}/.github/workflows/dev_pr/title_check.js`); 
        
                       script({github, context});

If it detects format mismatch, it adds a comment to notify it: https://github.com/apache/arrow/blob/main/.github/workflows/dev_pr/title_check.md

How about making the PR draft automatically in addition of the comment? Maintainers can ignore these PRs until they match our PR format.

@thisisnic

Sounds reasonable to me. I think the obvious offenders are the agent generated ones without human intervention, maybe the efforts from @thisisnic on adding new AGENTS.md files help with those.

Agreed! We just want to give clear human readable feedback to not introduce an unnecessary friction point.

Comments welcomed on #50375 if there are any other common AI failures we can try to account for.

Do we also perhaps want to add an auto-comment for issues which have been created without our issue template, and lack a "Type" and "Component" label as there are AI-generated ones which look like this and so are less likely to get in front of the relevant person.

@Reranko05

@Reranko05 Do you want to work on this?

@kou

@kou Sure! I'll take a look.
