The last_lts_mongos_commands.js & last_lts_mongod_commands.js files contain the list of commands added/removed on the router since the last LTS release.

These files were not properly sanitized once v6.0 branched out. Therefore, we must revisit them and ensure all commands on the lists were added/removed after v6.0; we can eliminate those commands that were added/removed either before v6.0 or on v6.0.X.

For example, setClusterParameter is on the list of commandsAddedToMongodSinceLastLTS but was actually introduced in v6.0 under SERVER-62265.

I recommend removing all the commands that are already in the last_lts_mongos_commands.js & last_lts_mongod_commands.js files in v6.0.
