Update Jira issues label colors
Because the colors in Jira hold meaning, we need to make sure that when we display the Jira issue data in GitLab, that we translate/transfer the colors over accurately.
Label colors in GitLab should be consistent with those that are found in Jira:
- Background: #EBECF0
- Text color: #283856
Closes #227475 (closed)
