Remove recommendation for creation of labels

[Ein-Tim]

This PR removes the recommendation to add labels to PRs and issues in CONTRIBUTING.md because community members do not have privileges to create labels in this repository (text adapted from here)

This has been done

• in the Android repository: Remove recommendation to create labels in new issues (COMMUNITY) cwa-app-android#2122
• in the Website repository: CONTRIBUTING - Remove labelling suggestion for outside contributors cwa-website#652

@Ein-Tim ok, I see. There are certain labels the community can use. Maybe it would be nice to include a sentence to use one of the available labels (bug, question, enhancement, ...) ?

Removed sencence:

• Please apply one or more applicable labels to your issue so that all community members are able to cluster the issues better.

Yes we could for sure go that way, I took the PR from @heinezen back in the website repo as basis, he removed the suggestion completely, so I also removed it.

Just let me know what you want 👍

Community members do not have the privileges to add or remove labels. Labels like "Bug" are added through one of the files in ISSUE_TEMPLATE. The label depends on which issue type the user chooses when they open a new issue and it can't be changed by the user subsequently. That is only something that somebody with more privileges can do. I can't see how that works exactly because I am only a Contributor so I don't have view access to the Settings of this repository!

@Ein-Tim's PR looks good; completely removing the sentence as was already done in the other repositories.

Mike is correct in that non-members cannot assign or remove labels by themselves. The chosen template decides the initial labels of an issue.

Makes sense. Let's do it.
