Support Maven pom with dependencies as input to the tool

We would like to propose to support Maven pom file as an input to the plugin manager tool.
E.g.
```

org.jenkins-ci.plugins
git
4.4.1

```
This way we can use dependabot in our repository to check for updates and create PRs, if an update is available. At the moment keeping an eye on the updates requires too much of our time, the same can be said regarding the equivalent implementation of the dependabot using the plugin manager tool.

We love reusing/contributing to existing tools.

What do you think about it? Have you tried anything similar already? Have we missed an important detail, that can block the implementation of this feature?
