Redis [BUG] RESP3 spec "Exponential format is invalid" but redis returns them

Describe the bug

According to the RESP3 spec, under floats, it says "Exponential format is invalid", although Redis returns floats on exponent format.

To reproduce

$ telnet localhost 6379
Trying ::1...
Connected to localhost.
Escape character is '^]'.
hello 3
(...snip...)
zadd z 1e100 highnumber
:1
zscore z highnumber
,1e+100

Expected behavior

Expect the RESP3 spec to match the actual Redis behaviour.

Additional information

It'd be a breaking change to change this in Redis, so I suggest updating the RESP3 spec instead.

Well that makes my ticket on the old spec repo doubly funny: https://github.com/antirez/RESP3/issues/37 :)
