Vulnerabilities that will be fixed

By pinning:

Severity	Priority Score (*)	Issue	Upgrade	Breaking Change	Exploit Maturity
	556/1000 Why? Recently disclosed, Has a fix available, CVSS 5.4	Cross-site Scripting (XSS) SNYK-PYTHON-MISTUNE-2328096	mistune: 0.8.4 -> 2.0.1	No	No Known Exploit

(*) Note that the real score may have changed since the PR was raised.

Some vulnerabilities couldn't be fully fixed and so Snyk will still find them when the project is tested again. This may be because the vulnerability existed within more than one direct dependency, but not all of the effected dependencies could be upgraded.

Check the changes in this PR to ensure they won't cause issues with your project.

Related issue: #6624

Seems that sphinx-contrib/openapi has not been updated for over a year. Unless we remove this dependency, we have to pin an older version of mistune.

@devos50 thank you for clarifying this.

The snyk issue will be ignored for the upcoming 3 months.
