Fix: Sort Teams in Metadata alphabetically

[GODrums]

Motivation

The current list of teams in the "Select team"-filter can be super confusing due to a lack of ordering.

Description

This PR sorts the list of teams in the metadata (GET /meta) alphabetically. The "all"-option will nevertheless always stay the first one and is selected as default.
