Update docker-compose-common-components.yaml (#1207)

The default 100 max postgres connections isn't enough when managing more than 4 (?) game servers, triggering http 502 errors in UI (see : https://discord.com/channels/685692524442026020/685695097349734469/1470638305606373452).

This fix increases the default to 300. This arbitrary number should suffice for a number of managed game servers up to 8, but still has to be evaluated in real conditions and edge cases (8+ servers).
