This reverts #27520 commit 79e8865aae
which breaks `--continue` functionality.

This script was trying to be too smart, make it more straightforward and
less error-prone so that i could be used by the backport bot too
ideally.

- Always delete the backport branch so that script is idempotent in this
regard
- Remove the push functionality, it's best done by the user because only
they know the remote name
- Remove reading docs/config.yaml, it no longer exists
- Remove version detection, version is now a required argument
- Remove opening the pull request with xdg-open, xdg-open is not
portable
- Remove continue from failed cherry pick. It's best to reset manually
in this case
- Clean up the console logging

Example run:

```
$ go run ./contrib/backport --version v1.21 27503
* Backporting 27503 to origin/release/v1.21 as backport-27503-v1.21
* `git fetch origin main`
* `git fetch origin release/v1.21`
* `git branch -D backport-27503-v1.21`
* `git checkout -b backport-27503-v1.21 origin/release/v1.21`
* Attempting git cherry-pick 08efeb5cdc
* Amending commit to prepend `Backport #27503` to body
Backport done! You can now push it with `git push yourremote backport-27503-v1.21`
```

Replace #10912

And there are many new tests to cover the CLI behavior

There were some concerns about the "option order in hook scripts"
(https://github.com/go-gitea/gitea/pull/10912#issuecomment-1137543314),
it's not a problem now. Because the hook script uses `/gitea hook
--config=/app.ini pre-receive` format. The "config" is a global option,
it can appear anywhere.

----

## ⚠️ BREAKING ⚠️

This PR does it best to avoid breaking anything. The major changes are:

* `gitea` itself won't accept web's options: `--install-port` / `--pid`
/ `--port` / `--quiet` / `--verbose` .... They are `web` sub-command's
options.
    * Use `./gitea web --pid ....` instead
* `./gitea` can still run the `web` sub-command as shorthand, with
default options
* The sub-command's options must follow the sub-command
* Before: `./gitea --sub-opt subcmd` might equal to `./gitea subcmd
--sub-opt` (well, might not ...)
    * After: only `./gitea subcmd --sub-opt` could be used
    * The global options like `--config` are not affected

The new `go-github` version
[53](https://github.com/google/go-github/releases/tag/v53.0.0) has been
released.

based on https://github.com/google/go-github/pull/2743

Enable [forbidigo](https://github.com/ashanbrown/forbidigo) linter which
forbids print statements. Will check how to integrate this with the
smallest impact possible, so a few `nolint` comments will likely be
required. Plan is to just go through the issues and either:

- Remove the print if it is nonsensical
- Add a `//nolint` directive if it makes sense

I don't plan on investigating the individual issues any further.

`github.com/google/go-github` has new major version releases frequently.
It is required to update all import path, in additional to `go.mod`

Sometimes it can be helpful to continue from a broken cherry-pick. This
PR adds another option which can be used to determine the version and pr
number from the current branch name instead of reading the config.yaml
file.

This PR provides a contributed backport command to help create backports
for Gitea.

It represents a significant improvement on my previously described
shell-script.

It can be installed using `go install contrib/backport/backport.go`.
