This adds a `/opt/appsmith/info.json` file to Docker images, with the
following sample content:
```json
{
"commitSha": "0521ba2c0d7a62cef3d4def66fc15b59cc34ceef",
"commitUrl": "0521ba2c0d",
"branch": "release",
"date": "2023-08-02T12:52:53+00:00",
"isCI": false
}
```
We're enabling this only for images built for DPs currently, and will
then extend to other workflows as well.
Notice that we copy `info.*json` instead of `info.json`. The reason is
so that the Docker build doesn't fail, even if the `info.json` file
doesn't exist. This lets us publish this to each workflow in turn,
slowly and carefully.
