fix(lambda): making metric change for serverless land (#6766)

## Problem
Earlier we recorded the pattern name based on the asset name, which
resulted in multiple records for the same template. This occurred
because the asset name included the runtime name as well.

## Solution
Modified the metric recording process to capture the pattern name, which
remains consistent across runtimes. This approach ensures there is a
single entry for each pattern, regardless of the runtime utilized. The
runtime information is recorded separately.
