When using a custom ROMM_BASE_PATH, the symbolic links used by nginx to serve assets were not being updated to point to the correct location, and always used the default `/romm` base path. This change introduces a fix in the `docker-entrypoint.sh` script, so those symbolic links are updated to point to the correct location set by the `ROMM_BASE_PATH` environment variable. Fixes #1626.
