[Management] Add share as a required dependency (#144381)

## Summary

This PR adds `share` as a required plugin of `management` plugin. 

I created a new plugin and was trying to add "management" as a
dependency. This was throwing an error when starting Kibana:
```
TypeError: Cannot read properties of undefined (reading 'url')
    at ManagementPlugin.setup (plugin.ts:42:1)
```
caused by:
https://github.com/elastic/kibana/blob/main/src/plugins/management/public/plugin.ts#L78

It looks like `share` was declared as an optional plugin but it didn't
handle a scenario when it was not provided.
