rename lektor config as gitlab project name, in line with other lektors.
this is needed for tpo/community/l10n#40049 (closed) to work, and already done in the support portal by lavamind at support@c15f0333
otherwise the job is broken, see for example: https://gitlab.torproject.org/tpo/web/gettor-web/-/pipelines/25855
