Fix #25776. Close #25826.

In the discussion of #25776, @wolfogre's suggestion was to remove the
commit status of `running` and `warning` to keep it consistent with
github.

## :warning: BREAKING :warning:

So the commit status of Gitea will be consistent with GitHub, only
`pending`, `success`, `error` and `failure`, while `warning` and
`running` are not supported anymore.

With the introduction of Actions, the pending commit icon has changed
from yellow to grey for Drone integrations which never set the "running"
status, so it stays in "pending" until completion.

I find it better to have this icon colored like on 1.19. Now both the
"pending" and "running" icons look the same, but I guess we could add an
animation to the "running" state similar to GitHub has to it later.

Also, it matches GH's icon:

### Reference and Inference
According to Github REST API
[doc](https://docs.github.com/en/rest/commits/statuses?apiVersion=2022-11-28#list-commit-statuses-for-a-reference):
1. The `Drone CI` that can create some commit status by
[API](https://docs.github.com/en/rest/commits/statuses?apiVersion=2022-11-28#create-a-commit-status)
is enabled in `go-gitea/gitea`. So I tried to call the API to get a
commit status list of a PR which is commited to upstream
repo(`go-gitea/gitea`). As a result, the API returned a array of commit
status.

![image](https://user-images.githubusercontent.com/33891828/223913371-313d047a-5e2e-484c-b13e-dcd38748703e.png)
2. Then I tried to call the API to get commit status list of the
reference which of the `SHA` is the same as step 1 in the repo which is
forked from `go-gitea/gitea`. But I got a empty array.

![image](https://user-images.githubusercontent.com/33891828/223930827-17a64d3c-f466-4980-897c-77fe386c4d3b.png)

So, I believe it that：
1. The commit status is not shared between upstream repo and forked
repo.
2. The coomit status is bound to a repo that performs actions. (Gitea's
logic is the same)

### Cause
During debugging, I found it that commit status are not stored in the DB
as expected.
So, I located the following code:

8cadd51bf2/services/actions/commit_status.go (L18-L26)
When I create a PR, the type of `event` is `pull request`, not `push`.
So the code return function directly.
