(gdk component publish): publish config not taken into account when running gdk component publish

[brnaba-aws]

Describe the bug
in gdk-config.json, there is the possibility to set a bucket and region json object:

"publish": {
        "bucket": "my-bucket",
        "region": "us-east-1"
      }

when running gdk component publish, it fails with this error:

Failed to create the bucket 'my-bucket-us-east-1-0123456789012' in region 'us-east-1'

To Reproduce
Use the above publish config and run. gdk component publish

Expected behavior
bucket and region should be used not formatted from bucket, region and account id

Workaround
run gdk component publish with args e.g:

gdk component publish --bucket my-bucket --region us-east-1
