Show number of total citations of an entry

[ThiloteE]

Problem:
There is metadata out there that JabRef is unable to capture (yet). One type of this data is the total number of an entry being cited.

Describe the solution you'd like

Show the number of total citations of an entry somewhere.

Additional context

• This issue is inspired by the following feature request in the forum: https://discourse.jabref.org/t/number-of-paper-citation-information/2616
• this issue here is a sub-issue of the more general issue of showing more citation-related diverse metadata, such as information about the journal, author and so on. A related issue would be Show information about the journal #6189

To do:

• Implementation difficulties:
  • Discussion is necessary to decide, where exactly the total number of citations should show in JabRef. Screenshots would be good.
  • Prefered: Finding public sources that do not require an API key.
    • If no public sources can be found, implement a solution that works, if users insert their own personal API key.

I'd like to investigate this further and work on this issue, can it be assigned to me? I'll be working with one other person so we should be able to get it done

You are welcome. If you really want to, you can of course, but since you are new to GitHub, I assume this is your first or second Open Source project. We have explicitly collected good first issues for newcomers and we also have candidates for university projects. If you ever feel like you are stuck, because this issue here is unexpectedly difficult and hard to achieve, you could instead have a look at those. If you ever decide to stop working on this, please comment here, so that we know.

As a general advice, check out https://github.com/JabRef/jabref/blob/main/CONTRIBUTING.md for a start. Also, https://devdocs.jabref.org/getting-into-the-code/guidelines-for-setting-up-a-local-workspace is worth having a look at. Feel free to ask if you have any questions here on GitHub or also at JabRef's Gitter chat.

Please also read into existing code at #7160.

Thanks ThiloteE and koppor - I'll let you know if we have any issues and will investigate #7160.

The number of citations and references can be provided by the SematicScholar API. It should be fairly easy to integrate it within the Citations relations tab.

@koppor @ThiloteE If you agree with the approach, I'll make a good first issue of this once I'm done with https://github.com/JabRef/jabref-issue-melting-pot/issues/281.

Sure, if you believe it will be easy, a fast win and you feel motivated, go for it :-)
