Fix TRUST_PROXY quotes

[J4NS-R]

At the moment, the env var PEERTUBE_TRUST_PROXY gets rendered like so:

- name: PEERTUBE_TRUST_PROXY
  value: "['10.0.0.0/8']"

This is actually invalid json. Strings in json have to use double-quotes. The startup logs confirm this:

SyntaxError: __format parser error in PEERTUBE_TRUST_PROXY: Unexpected token ' in JSON at position 1
    at JSON.parse (<anonymous>)
    at Parser.jsonParser (/app/node_modules/config/parser.js:158:17)
    at Config.util.parseString (/app/node_modules/config/lib/config.js:898:12)
    at _substituteVars (/app/node_modules/config/lib/config.js:1103:36)

    at Config.util.loadFileConfigs (/app/node_modules/config/lib/config.js:701:28)
    at new Config (/app/node_modules/config/lib/config.js:113:27)

Flipping around the quotes should fix the problem.
