Fixing capitalization in words with any dashes

[jvsdurso]

Fixes #9068

What: Fixing capitalization after dashes. Also covering zero width spaces. Tests were implemented too.

Why: To solve the issue #9068

Context: I'm having some classes about TDD (Test-Driven Development) and we were asked to solve an issue from JabRef. I chose to work on this one.

• Change in CHANGELOG.md described in a way that is understandable for the average user (if applicable)
• Tests created for changes (if applicable)
• Manually tested changed features in running JabRef (always required)
• Screenshots added in PR description (for UI changes)
• Checked developer's documentation: Is the information available and up to date? If not, I outlined it in this pull request.
• Checked documentation: Is the information available and up to date? If not, I created an issue at https://github.com/JabRef/user-documentation/issues or, even better, I submitted a pull request to the documentation repository.

Hi @jvsdurso , that is for you interest in jabref.
However I noticed some issues.

• changelog entry is only needed once.
• since java18 the idk works completely with utf 8. So you could probably use clear Unicode text instead of escaped characters. That would improve the readability a lot.
• also the tests seem to be very similar and probably could be parameterized.

Changes were made. I think leaving the tests with zero width spaces in Unicode may be better for visualization.
