[BUG] `message` does not attach to a file and line provided, and instead all comments are in the "main comment" section

[kadoshms]

Describe the bug

Seems like using the message API with a file and line doesn't always add the message as a comment on the file.
I would expect that for instance passing a foo.ts with line 6, would add the comment as follows:

Instead, the message is created under the "main comment" only - with the following format:

{FILE_PATH}:L{LINE_NUMBER} - message

To Reproduce
Steps to reproduce the behavior:

1. Create a danger rule with message on a file and line
2. Create an MR on GitLab Self-Hosted

Expected behavior
If provided, message should be inline to the file and line as a comment.

Screenshots
See above

It’s likely the issue is in one of the following files

• https://github.com/danger/danger-js/blob/main/source/platforms/gitlab/GitLabAPI.ts
• https://github.com/danger/danger-js/blob/5edb114d07d57292c707bba1dd72b129edd2f44f/source/ci_source/providers/GitLabCI.ts

Possibly in optional APIs that you need to override, or in how they’re submitting messages to the GitLab APIs

I don’t use GitLab, but somebody who does can probably figure it out from there! — (Does GitLab support line-level comments via API?)
