Weekday not updating in gantt chart

[DTGitRepository]

Describe the bug
When setting "weekday": "monday", it is not reflected in the output file.
My understanding is that the x-axis labels should now be monday dates, please correct me if I have misunderstood.
mermaid-js/mermaid#4634

To Reproduce
As above

Expected behavior
The week markers on the x-axis are updated to the relevant weekday value.
