Extend prettier setup

The classes looked horrible.

• eslint now triggers in pre-commit
• prettier tailwind classes added to dev dependencies for cleaner tailwind classes

I tried rebasing, but now I'm stuck at a weird issue with prettier that I don't know how to resolve. It's determined to add a line containing only spaces, on line 117 of frontend/src/components/TemplateDetails.jsx:

https://github.com/DSD-DBS/capella-model-explorer/pull/40/files#diff-5d2e1b4fa1fbce56d2f60962989f23143e0a162127bff9b32980388810ed5bcfR117

This causes a clash with the trailing-whitespace hook. @freshavocado7 do you have an idea about this, or can take another look? Maybe it's a lot simpler than I think.

After a lot of back and forth with prettier i decided to just resolve it with string concatenation. Also added some more prettier-eslint configurations.
