Remove 'Redis' in error replies

[zuiderkwast]

Low-risk error replies containing "Redis" are changed, excluding the following ones that are instead covered in #274 (since they're high risk of causing problems):

• (not in scope) "-MISCONF Redis is configured to save RDB snapshots (...)"
• (not in scope) "-LOADING Redis is loading the dataset in memory"
• (not in scope) "-BUSY Redis is busy running a script (...)"

Additionally, error replies from redis.call in a Lua script are affected, such as

• "Please specify at least one argument for this redis lib call"
• "Wrong number of args calling Redis command from script"
• "Unknown Redis command called from script"
• "Invalid command passed to redis.acl_check_cmd()"

The name Redis is simply removed from these error message. In the last one above, "redis.acl_check_cmd()" is replaced by "server.acl_check_cmd()" in the error message.

Fixes #204

For release notes:

The word "Redis" is removed in the following error replies:

• "This Redis instance is not configured to use an ACL file. You may want to specify users via the ACL SETUSER command and then issue a CONFIG REWRITE (assuming you have a Redis configuration file set) in order to store users in the Redis configuration."
• "Active defragmentation cannot be enabled: it requires a Redis server compiled with a modified Jemalloc like the one shipped by default with the Redis source requires a server compiled with a modified Jemalloc like the one shipped by default with the Valkey source distribution"
• "Wrong number of args calling Redis command from script"
• "Unknown Redis command called from script"

The words "used by Redis" are removed in the error message

• "The event loop API used by Redis is not able to handle the specified number of clients"

The words "since Redis 4" are removed in the error message

• "WAIT cannot be used with replica instances. Please also note that since Redis 4.0 if a replica is configured to be writable (which is not the default) writes to replicas are just local and are not propagated."

The words "redis lib" are removed from in the error message

• "Please specify at least one argument for this redis lib call"

"Lua redis lib command" replaced with just "Command" in the error message

• "Lua redis lib command arguments must be strings or integers"

"redis.acl_check_cmd" replaced by "server.acl_check_cmd" in the following error message:

• "Invalid command passed to redis.acl_check_cmd()"

@0del do you want to review this one?

LGTM !

I don't think we should make this change. We should use the indirection mechanism established in #47 instead. As we discussed in other threads, I am proposing to have one uber compilation flag such as '-DREDIS_COMAPT=1' to control the presence/absence of all breaking changes.

@valkey-io/core-team After decision made about #274, I've reduced the scope of this PR to only include "low risk" error replies. The "high risk" ones are handled in #274 instead.

I consider the scope of this PR (and the linked issue) already decided. It just needs a second review before merge.
