Intercept Azure webhooks and relay them to Discord with an accessible URL

[MarkKoz]

By default, the webhooks sent by Azure use a link which requires an authorised account to access. If the site intercepts the webhook, modifies the field for the URL, and sends it back out again, developers will be happier and more productive!

Here is the URL the webhook currently uses:

https://dev.azure.com/python-discord/web/build.aspx?pcguid=a4900c06-bea4-4b1b-930f-7bd7a2e05a22&builduri=vstfs%3a%2f%2f%2fBuild%2fBuild%2f6105

A more accessible URL for the same build is:

https://dev.azure.com/python-discord/Python%20Discord/_build/results?buildId=6105

Here is the documentation of the Azure webhook payload. message.markdown and detailedMessage.markdown are probably the relevant fields.

We're no longer using Azure, so this issue can be closed. The GitHub Action workflow webhooks are not perfect either, but that's worth a separate discussion is less related to the issue here.
