fix parsing human time output like "50m37s" (#10001)

## Problem

In ingest_benchmark.yml workflow we use pgcopydb tool to migrate
project.
pgcopydb logs human time.

Our parsing of the human time doesn't work for times like "50m37s".

[Example
workflow](https://github.com/neondatabase/neon/actions/runs/12145539948/job/33867418065#step:10:479)

contains "57m45s"

but we
[reported](https://github.com/neondatabase/neon/actions/runs/12145539948/job/33867418065#step:10:500)
only the seconds part: 
45.000 s


## Summary of changes

add a regex pattern for Minute/Second combination
