Disable work signing by default in dev env

Certs are generated on the host and there is currently an issue due to openssl version mispatch between Fedora 36 and CentOS Stream 8 which causes:

tools_awx_1     | ERROR 2022/11/15 17:09:17 could not load signing key file: unknown block type PRIVATE KEY
