RFR: 1823: Mailing list bot should include link to comment on the Git forge [v5]

[Zhao Song]

> This patch will add the ability to attach comment/reviewComment/review link to the email generated by mlbridge bot
> 
> The implementation for GitHub is straightforward, we can extract the URL for a specific comment or review from the JSON response using the `html_url` field and include it in the email. 
> 
> For GitLab, we will need to generate the URL using the `id` field in `note,` since GitLab does not provide an field like `html_url` in its JSON responses.
