This is a followup to #9656 and implements the following step mentioned in that PR:
* When possible, extract all the help and completion tips from COMMAND DOCS (Redis 7.0 and up)
* If COMMAND DOCS fails, use the static help.h compiled into redis-cli.
* Supplement additional command names from COMMAND (pre-Redis 7.0)
The last step is needed to add module command and other non-standard commands.
This PR does not change the interactive hinting mechanism, which still uses only the param
strings to provide somewhat unreliable and inconsistent command hints (see #8084).
That task is left for a future PR.

As far as i can tell it shows up in redis-cli in both HELP, e.g.
`help client list`, and also in the command completion tips, but it is
unclear what it was needed for.
It exists since the very first commit that added this mechanism.
Once this is merged:
- merge the latest changes to commands.json in antirez/redis-doc
- re-run: utils/generate-command-help.rb > src/help.h
Then we'll have nice and easy tab-completed help in redis-cli again.
Closes#1909
updated via commands.json in redis-doc repo. Currently
use `make src/help.h` to re-generate. The following
are valid from the REPL:
help
help [command]
help [group]
help groups
ex:
help sort
help hash
