ref(aws,gcp): Change timeout message

[sentrivana]

Description

The timeout in the AWS Lambda (and GCP, by extension) timeout warning is wrong, remove it and slightly rephrase.

This is on the new major branch since it breaks grouping. (Even just removing the number from the original message, without modifying it further, causes regrouping. Since that's the case I took the liberty to update the message a bit more.)

Original POTel PR: #4671
