Lectures: Add spacing between categories and correct alignment

[laxerhd]

Opening this PR from a branch in the main repository to enable test server deployment, as it wasn't possible with the previous PR from a forked repository (see #9860)

Checklist

General

• I tested all changes and their related features with all corresponding user types on a test server.
• This is a small issue that I tested locally and was confirmed by another developer on a test server.
• Language: I followed the guidelines for inclusive, diversity-sensitive, and appreciative language.
• I chose a title conforming to the naming conventions for pull requests.

Client

• I strictly followed the client coding and design guidelines.
• Following the theming guidelines, I specified colors only in the theming variable files and checked that the changes look consistent in both the light and the dark theme.

Changes affecting Programming Exercises

• High priority: I tested all changes and their related features with all corresponding user types on a test server configured with the integrated lifecycle setup (LocalVC and LocalCI).
• I tested all changes and their related features with all corresponding user types on a test server configured with Gitlab and Jenkins.

Motivation and Context

The missing spaces between the categories/tags didn't look natural.
The offset also bothered me. Fixes #9857.

Description

I've added some space between the categories and fixed the misalignment of the them.

Steps for Testing

• I (as a reviewer) confirm that the server changes (in particular related to database calls) are implemented with a very good performance even for very large courses with more than 2000 students.
