gettingstarted-limits - KiB or KB to define MB as MiB

[crisman]

https://github.com/awsdocs/aws-lambda-developer-guide/blob/main/doc_source/gettingstarted-limits.md

or

https://docs.aws.amazon.com/lambda/latest/dg/gettingstarted-limits.html

have this note:

The Lambda documentation, log messages, and console use the abbreviation MB (rather than MiB) to refer to 1024 KB.

which is painfully circular.

Is KB supposed to be 1000 bytes or 1024 bytes?

Please include if KB should be read as KiB.

Also include what GB should mean as Container image uses GB.
