Create initial Jira dashboards in Superset

In order to support items 43-44 in https://github.com/orgs/ISISNeutronMuon/projects/12/views/1 we need to create a space to visualize the data in that has been ingested in #434 and transformed in #438. As the first step we will build the dashboards in the local setup as we have not yet deployed a Superset instance for this type of data.

This task is to:

- Learn how to create charts and dashboards in [Apache Superset](https://superset.apache.org/user-docs/using-superset/creating-your-first-dashboard#registering-a-new-table) using the local version http://localhost:50080/workspace/facility_ops.
- In the local Superset decide and implement the appropriate visualizations within a dashboard called "Computing Jira" for:

- [ ] Each of the "time in status" tables from #438 separately
- [ ] Data Driven Facility
- [ ] Scientific Software
- [ ] Computing Infrastructure
- [ ] User Software
- [ ] The number of issues by "Type", including both open and closed.
- [ ] The number of issues by "Type" including only open issues

The chart and dashboard definitions are stored in the Superset internal database. This means there are no code definitions to commit to the repository.

In terms of backup this script [export_superset_dashboards_from_local.sh](https://github.com/user-attachments/files/32339468/export_superset_dashboards_from_local.sh) can be downloaded and used to extract the Dashboard and chart definitions to a local zip file.
