Resolve "Command to generate the gitlab-shell secret fails on Mac"
Add the LC_CTYPE=C definition to the tr call as part of the secrets generation in doc/installation/secrets.md.
This enforces C LANG and thus ANSI behaviors on the bytes provided from /dev/urandom by the tr command.
Also add secret generation for Redis, instead of commentation on pulling from 1Password
