Redis [BUG] bitfield returns empty array when required args are missing

Describe the bug

BITFIELD isn't in agreement with its COMMAND DOCS descriptor when missing a required argument.

To reproduce

BITFIELD mykey
(empty array)

Expected behavior

BITFIELD mykey
(error) ERR wrong number of arguments for 'bitfield' command

because the documentation and COMMAND DOCS descriptor both indicate at least one GET or SET must be specified.

My app that relies on the descriptor doesn't agree with redis-cli.

Additional information

Redis server v=7.0.8 sha=00000000:0 malloc=jemalloc-5.2.1 bits=64 build=8b9bd5cdb53a6549

thanks for the report, although I believe we should throw a error in that case, the argument became optional in #11445 we will release it in the next version (7.0.9). FYI @oranagra i added it in to the Redis 7.0 Backport
