Eugene Dyudyunov	7dfbd44552	fix: post sharing URL When MFE uses path-based deployment (common domain for all MFEs divided by path) - the copied link leads to 404 error. The fix: - construct a Post URL using MFE's `PUBLIC_PATH` env var - works for both subdomain and subdirectory-based deployments Note: LMS recently started to use the discussions sidebar which has the same button "Copy Link", but it uses its own env variable `DISCUSSIONS_MFE_BASE_URL`	2023-02-24 16:52:10 +02:00

This implements just that: by avoiding making configuration values constant, it should now be possible to change them after initialization.
