Issue:
Generic package from registry can't be extracted
Hi everyone 👋 

I'm using GitLab registry to push an asset with the format `gzip compressed data` (.tar.gz) but when I download the uploaded package, I can't decompress it.

Follow my `.releaserc.yml`

```yaml
branches:
  - "main"
plugins:
  - "@semantic-release/commit-analyzer"
  - "@semantic-release/release-notes-generator"
  - - "@semantic-release/exec"
    - verifyConditionsCmd: 'tar -czf package.tar.gz --exclude=".git*" --exclude="__pycache__" aws/'
  - - "@semantic-release/gitlab"
    - assets:
        - path: "package.tar.gz"
          filepath: "/package.tar.gz"
          label: "package.tar.gz"
          target: generic_package
          status: default
tagFormat: ${version}
```

If we do a `cat` to the package file, we will see weird data on top and at the end of the file.

```bash
❯ cat package.tar.gz
----------------------------636039438515691214353669
Content-Disposition: form-data; name="file"; filename="aws.tar.gz"
Content-Type: application/gzip

<REDACTED BINARY DATA>
----------------------------636039438515691214353669--
```

If we remove the first 4 files from the file with the command `sed -e '1,4d' < package.tar.gz > package2.tar.gz`, we will decompress it.

If we compress the file manually, upload it, and download it after we can decompress it since the data are been untouched.

Can someone give any insight?

fix(generic-package): fix issues when uploading multiple assets
This should fix #490 (WIP). Working on it I found some issues which were not recognized yet:
- wrong README example
- missing proxy
- invalid URL if `gitlapApiUrl` is set
