Update mermaid dependency
Problem to solve
We seem to refer to a private fork of mermaid. This does not allow us to enjoy updates to mermaid
https://gitlab.com/gitlab-org/gitlab-ce/blob/master/package.json#L32
"[blackst0ne-mermaid](https://npmjs.com/package/blackst0ne-mermaid)": "^7.1.0-fixed",
Further details
This feature was implemented with https://gitlab.com/gitlab-org/gitlab-ce/merge_requests/15107 by @blackst0ne @DouweM
Newer versions of mermaid support for example: axisFormat %m/%d/%Y
for Gantt charts
Proposal
Update mermaid to main repository https://www.npmjs.com/package/mermaid with 8.0.0-rc.8
What does success look like, and how can we measure that?
We are able to enjoy features such as axisFormat %m/%d/%Y
for Gantt charts
