Broken Link about Heroku

[yorihito-tanaka]

It seems that a link in the documentation, which is supposed to provide guidance on using Heroku, is currently broken. The URL is:

https://docs.blackboard.com/lti/tutorials/py-lti-1p3#using-heroku

Would it be possible for you to fix this link? Having access to the correct information would greatly assist users like myself in deploying the pylti1.3-flask-example on Heroku successfully.
I appreciate the work you've put into developing pylti1.3 and look forward to your response.

This could be the new link: https://docs.anthology.com/docs/lti/tutorials/pylti13
