Gitea: [Feature request]: see the dependency graph of an issue

[tuxayo]

Some issues can have a lot of dependencies which also have dependencies. So and having a graph can help to know what to work on.
This is an example of how it looks on Bugzilla which has this feature:
https://bugs.koha-community.org/bugzilla3/showdependencygraph.cgi?id=15522
Note that it's clickable, the issue has a color according their status and hovering shows it's name.

Some parts of ui and code of git graah could be re-use to achieve something similar. Ex: https://gitea.com/alpinelinux/aports/graph
