Creates an endpoint to edit Issue Security Level via REST API

Update 7 March 2024:

These endpoints now exist but are still experimental https://developer.atlassian.com/cloud/jira/platform/rest/v3/api-group-issue-security-schemes/#api-rest-api-3-issuesecurityschemes-post

Original Description:

Problem Definition

At this moment, we don't have a REST API endpoint to edit Issue Security Levels. We can only GET the Issue Security Level in a given ID.

Suggested Solution

Implement an endpoint that would allow editing the Issue Security Level so that we can automate the management of the Issue Security Levels, especially when there are a lot of them.

Why this is important

This would make easier the management of the Security Level and we can also automate this management process.
