Decimal separator in items/containers.json breaks on my locale

[marningmol]

Starting or loading a game fails with a JSON error. Having had a similar issue #44608 a few days ago, I've taken the liberty to assume I know whats going on. The thousand separator in line 1637 and 1655 is parsed incorrectly due to locale issues.

Changing "max_contains_volume" from "1.25 L" to "1250 ml" on lines 1637 and 1655 in data/items/containers.json fixes the issues on my system.

Steps To Reproduce

1. Start / load a game on a system with incompatible locale.
2. While loading JSON files, the game will error complaining about "invalid quantity unit".

Expected behavior

A systems locale should not affect the functionality of the game.

Thanks. Has already been fixed by @Fris0uman in #44798.
