Remove usage of deprecated position argument for GitHub comments

[pbstriker38]

• This allows usage of Octokit v8.0.0

Fixes: #453

@pbstriker38 I'm not sure this works with older versions of octokit -- what do you think of bumping the dependency? Without verifying that it works, I'd be a bit hesitant to merge this as-is.

@ashkulz I did verify that it works with both versions. On Octokit 7.2.0 it sends both position and line params. The API ignores postion and uses line. On Octokit 8.0.0 the params are merged into the options and thus the line is merged.

The other option I can do here is to not use Octokit#create_pull_comment method and to just use Octokit#post directly like so:

options = {
  body: comment.body,
  commit_id: pull_sha || comment.sha,
  path: comment.path,
  line: comment.position
}
client.post("#{Octokit::Repository.path(slug)}/pulls/#{pull_id}/comments", options)

I did not test earlier Octokit versions though. I can try and test those too.

• 4.7.0
• 5.x.x
• 6.x.x

Thanks for the contribution and being patient while we figured things out, @pbstriker38!

0.11.3 has been released to RubyGems. Publishing future versions should be simpler due to implementation of Trusted Publishing workflow (c7007de) 😁
