Cannot fetch PR comments using `danger.api.github`

**_using 3.17.1 version_**

Hi

I need the comments from the PR to detect some stuff required for my rules processing.

_I think the way to do it should be to update GithubDSL to include the required structs._

What I'm doing

ActionFlow
```
name: Run Unit Tests

on:
pull_request:
types: [opened, synchronize]

jobs:
checkout_and_prepare:
[...]
test:
[...]
run-danger:
name: "Run Danger"
needs: test
runs-on: self-hosted
steps:
- name: Generate Github Token
id: generate_token
uses: tibdex/github-app-token@v1
with:
app_id: ${{ secrets.TOKEN_APP_ID }}
private_key: ${{ secrets.TOKEN_APP_PRIVATE_KEY }}
- name: Danger
run: |
sh FirstPartyFrameworks/My-CI/BuildTools/danger_lint.sh
env:
GITHUB_TOKEN: ${{ steps.generate_token.outputs.token }}
DANGER_GITHUB_API_TOKEN: ${{ steps.generate_token.outputs.token }}
```

**Note**
If I had this step before danger

```
- name: Test API Call
run: |
curl -H "Authorization: token ${{ steps.generate_token.outputs.token }}" \
https://api.github.com/repos///issues//comments
```

The curl succeeds.

Now, in my code, if I'm doing

```
danger.github.api.issueComments(owner: owner,
repository: repo,
number: danger.github.pullRequest.number)
```

Then I get

```
Error fetching comments: Error Domain=com.nerdishbynature.octokit Code=404
```

After digging, I honestly think that's an issue with Authorization. But I don't know how to setup it properly or if the library needs an update.
As I said, it might also be only a matter of mapping some properties in the `Github` struct.

Also, as a FYI, I have those warnings at then end:
