ping @xxchan for a look.

There are the following problems:

- The action won't work until we set go-storage to semver: Dependabot ignore git versions

• I don't know how to test this workflow.

Suggested change

	on: pull_request_target
	permissions:
	pull-requests: write
	contents: write
	on: pull_request

is enough?

[Xuanwo]

We need Auto commit & push, so write is required.

[xxchan]

I think we can test by removing dependency-names first?

[xxchan]

Wait, but we have to merge this into master first to test?

Yep, it's a problem. Maybe we can merge this to another branch?

[Xuanwo]

Here is an open PR from dependabot: #138

Maybe we can test via them instead.

I think this is an affordable price: one or two useless commit

Can it be triggered? I'm OK.

Ooops, it looks like we have to merge this PR into master first.
