Code-completion for a dependency/plugin's 'version' element only proposes locally available versions

[HannesWell]

When activating the Content-Assist in a pom.xml at the version element of a dependency and plugin it looks like only locally available version are proposed instead of all version available in the available repositories (e.g. Maven-Central).

The Maven-Resolver offers a simple API to obtain all available versions in a range, e.g. [0,) for all:

I don't know how lemminx-maven has implemented its proposals, but if one can guide me to the right location I can have a look at this.
