chore(core-database-postgres): use token in database name

[spkjp]

Proposed changes

#1970 changed the default name to core_${network}. This PR changes this to $token_$network so we get ark_devnet, etc. like before. It also ensures the names are distinct between different chains.

I would add a bash script in the scripts folder that can generate the docker files with the correct names.
