Add user documentation for SLR tool

[mannatjain11465-netizen]

Summary

This PR adds user documentation for the Systematic Literature Review (SLR) tool in JabRef.

The page explains how users can perform a structured literature review using the SLR feature, including:

• Defining study parameters (authors and title)
• Adding research questions
• Creating search queries
• Selecting academic catalogs
• Running and managing the survey
• Best practices for effective SLR workflows

This documentation is aimed at end users and helps make the SLR feature more discoverable and easier to use.

Motivation

The SLR tool is a powerful feature, but users may not know how to use it effectively. This documentation provides step-by-step guidance to support systematic and reproducible literature reviews.

Type of Change

• Documentation update

Checklist

• Documentation added in the user-documentation repository
• Content reviewed for clarity and consistency
• Follows existing documentation style

Also fixed pre-existing markdownlint issues in how-to-enable-and-use-ai-features.md so CI passes

OK, this reads like a nice AI-generated text.

Value comes in by:

1. Screenshots
2. Correct naming (I think, JabRef does not talk about "Tool" in the documentation)
3. Correct content.
4. More content than just listing what's in the UI
5. Linking other areas of the documentation
6. Same style as other areas of the documentation

Please submit unrelated fixes as seperate PR - to speed things up.

Clear sign of AI geneation.

concrete example still messing.

[koppor]

Please provide an example. A concrete study.

Do not just re-state what's shown in JabRef

This issue is NOT a quick win.

Use an existing SLR as example - or think of your own.

Maybe, it is easy to cover a part of https://link.springer.com/article/10.1007/s00607-025-01432-z in the documentation?

Example still missing

Thanks for the feedback! Just to confirm that I understand correctly, you’d like the documentation to include a more realistic example that reflects how an actual published study is structured rather than a simplified illustrative scenario. I'll update the example accordingly

Yes. And please double-check https://github.com/JabRef/jabref/blob/main/AI_USAGE_POLICY.md#guidelines-for-using-ai-tools

Will it be fine if the screening numbers are illustrative, to show how papers get filtered through the stages...and not from a real study since it's only an example or am I supposed to pick them from an actual study?

Do a mix of both. - I fear that "illustrative" could mean, you do "ABC", "DEF" and random stuff. This is not OK. - You are invited to come up with a "spontaneous" example. Maybe based on our "Chocolate" world: https://github.com/JabRef/jabref-demonstration-libraries/tree/main/chocolate. Not holistic, but the mains steps should be in.
